Upgrade is performed by updating node configuration (node by node, service
by service), watching internal resource state to get new configuration
version and verifying that pod with matching version successfully
propagated to the API server state and pod is ready.
Process is similar to the rolling update of the DaemonSet.

This is required to upgrade from Talos 0.8.x to 0.9.x. After the cluster
is fully upgraded, control plane is still self-hosted (as it was
bootstrapped with bootkube).
Tool `talosctl convert-k8s` (and library behind it) performs the upgrade
to self-hosted version.

Filesystem creation step is moved on the later stage: when Talos mounts
the partition for the first time.
Now it checks if the partition doesn't have any filesystem and formats
it right before mounting.
Additionally refactored mount options a bit:
- replaced separate options with a set of binary flags.
- implemented pre-mount and post-unmount hooks.
And fixed typos in couple of places and increased timeout for `apid ready`.

This allows to generating current version Talos configs (by default) or
backwards compatible configuration (e.g. for Talos 0.8).
`talosctl gen config` defaults to current version, but explicit version
can be passed to the command via flags.
`talosctl cluster create` defaults to install/container image version,
but that can be overridden. This makes `talosctl cluster create` now
compatible with 0.8.1 images out of the box.
Upgrade tests use contract based on source version in the test.
When used as a library, `VersionContract` can be omitted (defaults to
current version) or passed explicitly. `VersionContract` can be
convienietly parsed from Talos version string or specified as one of the
constants.

Modify provision library to support multiple IPs, CIDRs, gateways, which
can be IPv4/IPv6. Based on IP types, enable services in the cluster to
run DHCPv4/DHCPv6 in the test environment.
There's outstanding bug left with routes not being properly set up in
the cluster so, IPs are not properly routable, but DHCPv6 works and IPs
are allocated (validates DHCPv6 client).

Our upgrades are safe by default - we check etcd health, take locks,
etc. But sometimes upgrades might be a way to recover broken (or
semi-broken) cluster, in that case we need upgrade to run even if the
checks are not passing. This is not a safe way to do upgrades, but it
might be a way to recover a cluster.

ECDSA keys are smaller which decreases Talos config size, they are more
efficient in terms of key generation, signing, etc., so it makes boot
performance better (and config generation as well).

For single node clusters, control plane is unstable after reboot, run
health check several times to let it settle down to avoid failures in
subsequent checks.
Signed-off-by: Andrey Smirnov <smirnov.andrey@gmail.com>
Regular upgrade path takes just one reboot, but it requires all the
processes to be stopped on the node before upgrade might proceed. Under
some circumstances and with potential Talos bugs it might not work
rendering Talos upgrades almost impossible.
Staged upgrades build upon regular install flow to run the upgrade on
the node reboot. Such upgrades require two reboots of the node, and it
requires two pulls of the installer image, but they should be much less
suspicious to the failure. Once the upgrade is staged, node can be
rebooted in any possible way, including hard reset and upgrade is
performed on the next boot.
New ADV format was implemented as well to allow to store install image
ref/options across reboots. New format allows for bigger values and
takes 50% of the `META` partition. Old ADV is still kept for
compatibility reasons.

This is initial commit of the installer.
What's done:
- verifying node availability before starting any operations.
- gathering information about disks on the machine.
- allows setting: install disk, hostname, machine type, installer image,
kubernetes version, dns domain, cluster-name.
- dumps/merges talosconfig to a file after applying configuration.

Bump to 0.7.0 as we have a new release.
Clean up the tests we do: 0.6.3 is a previous release, 0.7.0 is a stable
release, current version (0.8.x) is the "next" release.
We test the following:
* 0.6.3 -> 0.7.0
* 0.7.0 -> 0.8-current
* 0.7.0 -> 0.8-current (single node)
This tests upgrades always between two releases.

This fixes the reverse Go dependency from `pkg/machinery` to `talos`
package.
Add a check to `Dockerfile` to prevent `pkg/machinery/go.mod` getting
out of sync, this should prevent problems in the future.
Fix potential security issue in `token` authorizer to deny requests
without grpc metadata.
In provisioner, add support for launching nodes without the config
(config is not delivered to the provisioned nodes).
Breaking change in `pkg/provision`: now `NodeRequest.Type` should be set
to the node type (as config can be missing now).
In `talosctl cluster create` add a flag to skip providing config to the
nodes so that they enter maintenance mode, while the generated configs
are written down to disk (so they can be tweaked and applied easily).

This enables golangci-lint via build tags for integration tests (this
should have been done long ago!), and fixes the linting errors.
Two tests were updated to reduce flakiness:
* apply config: wait for nodes to issue "boot done" sequence event
before proceeding
* recover: kill pods even if they appear after the initial set gets
killed (potential race condition with previous test).

By default, build outside of Drone works the same and builds only amd64
version, loads images back into dockerd, etc.
If multiple platforms are used, multi-arch images are built which can't
be exported to docker or to `.tar` image, they're always pushed to the
registry (even for PR builds to our internal CI registry).
Artifacts as files (initramfs, kernel) now have `-arch` suffix:
`vmlinuz-amd64`, `initramfs-amd64.xz`. "Magic" script normalizes output
paths depending on whether single platform or multiple platforms were
given.
VM provisioners accept magic `${ARCH}` in initramfs/kernel paths which
gets replaced by cluster architecture.

This change is only moving packages and updating import paths.
Goal: expose `internal/pkg/provision` as `pkg/provision` to enable other
projects to import Talos provisioning library.
As cluster checks are almost always required as part of provisioning
process, package `internal/pkg/cluster` was also made public as
`pkg/cluster`.
Other changes were direct dependencies discovered by `importvet` which
were updated.
Public packages (useful, general purpose packages with stable API):
* `internal/pkg/conditions` -> `pkg/conditions`
* `internal/pkg/tail` -> `pkg/tail`
Private packages (used only on provisioning library internally):
* `internal/pkg/inmemhttp` -> `pkg/provision/internal/inmemhttp`
* `internal/pkg/kernel/vmlinuz` -> `pkg/provision/internal/vmlinuz`
* `internal/pkg/cniutils` -> `pkg/provision/internal/cniutils`

* handle reboots in qemu launcher to support reset API case, update

* make bootloader support default in provisioners, and flag to disable
that
* early support for target architecture for qemu provisioner

Handling of multiple endpoints has already been implemented in #2094.
This PR enables round-robin policy so that grpc picks up new endpoint
for each call (and not send each request to the first control plane
node).
Endpoint list is randomized to handle cases when only one request is
going to be sent, so that it doesn't go always to the first node in the
list.
gprc handles dead/unresponsive nodes automatically for us.
`talosctl cluster create` and provision tests switched to use
client-side load balancer for Talos API.
On the additional improvements we got:
* `talosctl` now reports correct node IP when using commands without
`-n`, not the loadbalancer IP (if using multiple endpoints of course)
* loadbalancer can't provide reliable handling of errors when upstream
server is unresponsive or there're no upstreams available, grpc returns
much more helpful errors
