edb40437ec feat: add support for osctl logs -f
Now default is not to follow the logs (which is similar to `kubectl logs`).

Integration test was added for `Logs()` API and `osctl logs` command.

10a40a15d9 fix: extract errors from API response
This PR only touches `Version` method, but I will expand it to other
methods in the next PR.

When proxying to many upstreams, errors are wrapped as responses as we
can't return error and response from grpc call. Reflect-based function
was introduced to filter out responses which contain errors as
multierror. Reflection was used, as each response is a different Go
type, and we can't write a generic function for it.

osctl was updated to support having both resp & err not nil. One failed
response shouldn't result in error.

Re-enabled integration test for multiple targets and version
consistency, need e2e validation.

96a7289f06 test: fix integration version test as 'NODE:' might be missing
When invoked without `-t`, `osctl` shouldn't print `NODE:` anymore.

5b7bea2471 feat: use grpc-proxy in apid
This replaces codegen version of apid proxying with
talos-systems/grpc-proxy based version. Proxying is transparent, it
doesn't require exact information about methods and response types. It
requires some common layout response to enhance it properly with node
metadata or errors.

There should be no signifcant changes to the API with the previous
version, but it's worth mentioning a few changes:

1. grpc.ClientConn is established just once per upstream (either local
service or remote apid instance).

2. When called without `-t` (`targets`), apid proxies immediately down
to local service skipping proxying to itself (as before), which results
in empty node metadata in response (before it had local node IP). Might
revert this later to proxy to itself (?).

3. Streaming APIs are now fully supported with multiple targets, but
message definition doesn't contain `ResponseMetadata`, so streaming APIs
are broken now with targets (needs a fix).

4. Errors are now returned as responses with `Error` field set in
`ResponseMetadata`, this requires client library update and `osctl` to
handle it properly.

8c7fadde95 test: disable discovery-based test as it might break e2e
It seems to work reliably in basic-integration, but fails in e2e
(receives less responses than expected). We can re-enable once we get to
the root cause of the problem.

af2b6fa130 test: implement node discovery for integration tests
This adds support for node discovery for API-based tests, but discovery
is based on k8s state. Discovery can be overridden if we provide a list
of node IPs as a flag.

Also adds a test for K8s API server version.

63212ab17e test: fix integration test for k8s version
Push versions to constants, introduce 'platform' to version API to
discover node mode. Check kernel version for non-containers.

A bit of refactoring on version package to expose something closer to a
single response.

551fa45d33 test: add CLI integration test
This starts with a very simple test for `osctl version` using regexps as
output of the command depends a lot on current version.

We might use more of 'gold' matches for other commands potentially.

b0aef2cf22 test: add integration test framework
This is just first steps and core foundation.

It can be used like:

```
make integration.test
osctl cluster create
build/integration.test -test.v
```

This should run the test against the Docker instance.
