in development environment it could be beneficial not to use up that

Talos now supports new type of encryption keys which rely on Sealing/Unsealing randomly generated bytes with a KMS server:
```
systemDiskEncryption:
ephemeral:
keys:
- kms:
endpoint: https://1.2.3.4:443
slot: 0
```
gRPC API definitions and a simple reference implementation of the KMS server can be found in this
[repository](https://github.com/siderolabs/kms-client/blob/main/cmd/kms-server/main.go).

Add flags for configuring the qemu bridge interface with chaos options:
- network-chaos-enabled
- network-jitter
- network-latency
- network-packet-loss
- network-packet-reorder
- network-packet-corrupt
- network-bandwidth
These flags are used in /pkg/provision/providers/vm/network.go at the end of the CreateNetwork function to first see if the network-chaos-enabled flag is set, and then check if bandwidth is set. This will allow developers to simulate clusters having a degraded WAN connection in the development environment and testing pipelines.
If bandwidth is not set, it will then enable the other options.
- Note that if bandwidth is set, the other options such as jitter, latency, packet loss, reordering and corruption will not be used. This is for two reasons:
- Restriction the bandwidth can often intoduce many of the other issues being set by the other options.
- Setting the bandwidth uses a separate queuing discipline (Token Bucket Filter) from the other options (Network Emulator) and requires a much more complex configuration using a Heirarchial Token Bucket Filter which cannot be configured at a granular enough level using the vishvananda/netlink library.
Adding both queuing disciplines to the same interface may be an option to look into in the future, but would take more extensive testing and control over many more variables which I believe is out of the scope of this PR. It is also possible to add custom profiles, but will also take more research to develop common scenarios which combine different options in a realistic manner.

`config.Container` implements a multi-doc container which implements
both `Container` interface (encoding, validation, etc.), and `Conifg`
interface (accessing parts of the config).
Refactor `generate` and `bundle` packages to support multi-doc, and
provide backwards compatibility.
Implement a first (mostly example) machine config document for
SideroLink API URL.
Many places don't properly support multi-doc yet (e.g. config patches).

Fixes#6119
With new stable default hostname feature, any default hostname is
disabled until the machine config is available.
Talos enters maintenance mode when the default config source is empty,
so it doesn't have any machine config available at the moment
maintenance service is started.
Hostname might be set via different sources, e.g. kernel args or via
DHCP before the machine config is available, but if all these sources
are not available, hostname won't be set at all.
This stops waiting for the hostname, and skips setting any DNS names in
the maintenance mode certificate SANs if the hostname is not available.
Also adds a regression test via new `--disable-dhcp-hostname` flag to
`talosctl cluster create`.

Docker by default disable IPv6 completely in the containers which breaks
SideroLink on Docker-based clusters, as SideroLink is using IPv6
addresses for the Wiregurard tunnel.
This change might break `talosctl cluster create` on host systems which
have IPv6 disabled completely, so provide a flag to revert this
behavior.

Related to #4448
The only remaining part is filtering out SideroLink addresses when Talos
looks for a node address.
See also https://github.com/talos-systems/siderolink/pull/2
The way to test it out:
```
$ talosctl cluster create ... --extra-boot-kernel-args
siderolink.api=172.20.0.1:4000
```
(where 172.20.0.1 is the bridge IP)
Run `siderolink-agent` (test implementation):
```
$ sudo _out/siderolink-agent-linux-amd64
```
Now on the host, there should be a `siderolink` Wireguard userspace
tunnel:
```
$ sudo wg
interface: siderolink
public key: 2aq/V91QyrHAoH24RK0bldukgo2rWk+wqE5Eg6TArCM=
private key: (hidden)
listening port: 51821
peer: Tyr6C/F3FFLWtnzqq7Dsm54B40bOPq6++PTiD/zqn2Y=
endpoint: 172.20.0.1:47857
allowed ips: fdae:41e4:649b:9303:b6db:d99c:215e:dfc4/128
latest handshake: 2 minutes, 2 seconds ago
transfer: 3.62 KiB received, 1012 B sent
...
```
Each Talos node will be registered as a peer, tunnel is established.
You can now ping Talos nodes from the host over the tunnel:
```
$ ping fdae:41e4:649b:9303:b6db:d99c:215e:dfc4
PING fdae:41e4:649b:9303:b6db:d99c:215e:dfc4(fdae:41e4:649b:9303:b6db:d99c:215e:dfc4) 56 data bytes

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).

This refactoring is required to simplify the work to be done to support
disk encryption.
Tried to minimize amount of queries done by `blockdevice` `probe`
methods.
Instead, where we have `runtime.Runtime` we get all required blockdevices
there from blockdevice cache stored in `State().Machine().Disk()`.
This opens a way to store encryption settings in the `Partition`
objects.

If disk is empty and ISO path is given, QEMU provisioner mounts ISO on
the first boot.
To drop into maintenance mode:
```
talosctl cluster create --provisioner=qemu --iso-path=./_out/talos-amd64.iso --skip-injecting-config --wait=false
```
Then inject the config, bootstrap the node, wait for it to come up (via
`talosctl cluster health`).

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 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`
