Make ConfigOK status messages more human readable
This makes the ConfigOK status messages for dynamic config more human readable by including the path (e.g. SelfLink) to the object. The messages used to include the UID, but this was kind of useless, because there's no way to GET an object by UID.

periodically check whether assigned kubelet config should become last-known-good
Fixes#57808
Previously, the last-known-good was only updated on Kubelet restart. This has been on my todo list for a while, good to finally have a PR up.
Previously we could have this scenario, which is fixed by this PR:
- lkg is set to local
- we set config A
- config A passes trial period, but nothing caused Kubelet to restart
- we set config B, which turns out to be invalid
- Kubelet will fall back to local, because lkg was never updated

Avoid error on closed pipe

from @stevekuznetsov:
> If you do `echo | grep -q`, `grep` will exit when it finds the first match
> If the `echo` is still writing to stdout it fails because there's no reader on that pipe anymore
> So we always use `grep -q <<<"${content}"` now

RBD Plugin: Pass monitors addresses in a comma-separed list instead of trying one by one.
**What this PR does / why we need it**:
In production, monitors may crash (or have a network problem), if we try monitors one by one, rbd
command will hang a long time (e.g. `rbd map -m <unconnectable_host_ip>`
on linux 4.4 timed out in 6 minutes) when trying a unconnectable monitor. This is unacceptable.
Actually, we can simply pass a comma-separated list monitor addresses to `rbd`
command utility. Kernel rbd/libceph modules will pick monitor randomly
and try one by one, `rbd` command utility succeed soon if there is a
good one in monitors list.
[Docs](http://docs.ceph.com/docs/jewel/man/8/rbd/#cmdoption-rbd-m) about `-m` option of `rbd` is wrong, 'rbd' utility simply pass '-m <mon>' parameter to kernel rbd/libceph modules, which
takes a comma-seprated list of one or more monitor addresses (e.g. ip1[:port1][,ip2[:port2]...]) in its first version in linux (see 602adf4002/net/ceph/ceph_common.c (L239)). Also, libceph choose monitor randomly, so we can simply pass all addresses without randomization (see 602adf4002/net/ceph/mon_client.c (L132)).
From what I saw, there is no need to iterate monitor hosts one by one.

format error message and remove duplicated event for resize volume failure
**What this PR does / why we need it**:
1. The `operationGenerator.resizeFileSystem` method returns errors generated by `volumeToMount.GenerateErrorDetailed`, and the outside code(`operationGenerator.GenerateMountVolumeFunc`) uses `volumeToMount.GenerateError` to generate a new error again, which lead to the event message redundant and confused, we should use `volumeToMount.GenerateError` inside `operationGenerator.resizeFileSystem` only, in outside code is not necessary.
2. The `eventRecorderFunc` will record an event if `resizeFileSystem` returns an error, so we needn't to record event inside `resizeFileSystem` itself.

Add 'exec' in all saltbase manifests using '/bin/sh -c'.
Right now, if docker sends SIGTERM, /bin/sh doesn't pass it to
underlying process, which breaks graceful process shutdown.
Changing '/bin/sh -c CMD > /var/log/FILE.log' pattern to '/bin/sh -c
exec CMD > /var/log/FILE.log' still allows to redirect output to log
file, but also passes all signals to CMD process.

Fix PodCIDR flag: defaults come from the object, not as literal args to the flag function
The defaulter runs on the object before adding flags. Flags should be registered with defaults sourced from this object, so that the defaulter, not the flag var function, determines the canonical default value.

Replace --init-config-dir with --config
Rather than a directory with magic names, just give the Kubelet a file path.
Was originally in #55718, but I'm splitting it out for clarity.
Fixes#57763
```release-note
The alpha `--init-config-dir` flag has been removed. Instead, use the `--config` flag to reference a kubelet configuration file directly.
