Introduce networking/v1alpha1 api group.
Add `ClusterCIDR` type to networking/v1alpha1 api group, this type
will enable the NodeIPAM controller to support multiple ClusterCIDRs.
- add feature gate
- add encrypted object and run generated_files
- generate protobuf for encrypted object and add unit tests
- move parse endpoint to util and refactor
- refactor interface and remove unused interceptor
- add protobuf generate to update-generated-kms.sh
- add integration tests
- add defaulting for apiVersion in kmsConfiguration
- handle v1/v2 and default in encryption config parsing
- move metrics to own pkg and reuse for v2
- use Marshal and Unmarshal instead of serializer
- add context for all service methods
- check version and keyid for healthz

Flocker storage plugin removed from k8s codebase.
Flocker, an early external storage plugin in k8s,
has not been in maintenance and their business is
down. As far as I know, the plugin is not being
used anymore.
This PR removes the whole flocker dependency and
codebase from core k8s to reduce potential security
risks and reduce maintenance work from the sig-storage community.
Part of the API discovery cache uses an HTTP RoundTripper that
transparently caches responses to disk. The upstream implementation of
the disk cache is hard coded to call Sync() on every file it writes.
This has noticably poor performance on modern Macs, which ask their disk
controllers to flush all the way to persistant storage because Go uses
the `F_FULLFSYNC` fnctl. Apple recommends minimizing this behaviour in
order to avoid degrading performance and increasing disk wear.
The content of the discovery cache is not critical; it is indeed just a
cache and can be recreated by hitting the API servers' discovery
endpoints. This commit replaces upstream httpcache's diskcache
implementation with a similar implementation that can use CRC-32
checksums to detect corrupted cache entries at read-time. When such an
entry is detected (e.g. because it was only partially flushed to
permanent storage before the host lost power) the cache will report a
miss. This causes httpcache to fall back to its underlying HTTP
transport (i.e. the real API server) and re-cache the resulting value.
Apart from adding CRC-32 checksums and avoiding calling fsync this
implementation differs from upstream httpcache's diskcache package in
that it uses FNV-32a hashes rather than MD5 hashes of cache keys in
order to generate filenames.

This dependency was updated in 6b864dc4e1, but using
a version that's 1 commit ahead of the latest (v1.0.1) release. As a consequence,
any project that uses k8s.io/component-base as a dependency, but that prefers to
use tagged releases, will be required to add a `replace` rule in their `go.mod`.
Looking at the difference between the currently used version and the last release,
the only difference is the addition of a `go.mod`:
https://github.com/matttproud/golang_protobuf_extensions/compare/v1.0.1...c182affec369
While it can help to have a `go.mod` to resolve the minimum version of (indirect)
dependencies, in this case, the (minimum) versions of dependencies defined in this
module's `go.mod` are quite a bit behind the version defined in k8s' own go.mod,
so would already be up-to-date.
Based on the above, it looks like the `go.mod` (currently) doesn't provide much
value, and it would be safe to roll back 1 commit to use the tagged/released
version of this module.
