This is going to be useful in the third party code which is using
upgrade modules, to collect output logs instead of printing them to the
stdout.

The structure of the controllers is really similar to addresses and
routes:
* `LinkSpec` resource describes desired link state
* `LinkConfig` controller generates `LinkSpecs` based on machine
configuration and kernel cmdline
* `LinkMerge` controller merges multiple configuration sources into a
single `LinkSpec` paying attention to the config layer priority
* `LinkSpec` controller applies the specs to the kernel state
Controller `LinkStatus` (which was implemented before) watches the
kernel state and publishes current link status.

This extracts function which was used in upgrade/convert flows to retry
transient errors to the main `kubernetes` package, expands it to ignore
timeout errors, and it is now used to retry errors where applicable in
`pkg/kubernetes`.
Fixes#3403

Without loadbalancer, when api-server goes down, there will be
connection refused errors which should be retried.

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.
