* Move snapshot structs and functions into pkg/etcd/snapshot
* Move s3 client code and functions into pkg/etcd/s3
* Refactor pkg/etcd to track snapshot and s3 moves
* Add support for reading s3 client config from secret
* Add minio client cache, since S3 client configuration can now be
changed at runtime by modifying the secret, and don't want to have to
create a new minio client every time we read config.
* Add tests for pkg/etcd/s3

Fixes an issue where the semaphore wasn't permanently initialized
until a scheduled snapshot was taken, allowing multiple on-demand
snapshots to be taken until the first scheduled snapshot was triggered.

It is concievable that users might take more than 60 seconds to deploy their own cloud-provider. Instead of exiting, we should wait forever, but with more logging to indicate what's being waited on.

Start shared informer caches when k3s-etcd controller wins leader election. Previously, these were only started when the main k3s apiserver controller won an election. If the leaders ended up going to different nodes, some informers wouldn't be started

* Adds support for health-checking loadbalancer servers. If a
health-check fails when dialing, all existing connections to the
server will be closed.
* Wires up a remotedialer tunnel connectivity check as the health check
for supervisor/apiserver connections.
* Wires up a simple ping request to the supervisor port as the health
check for etcd connections.

If a full reconcile wins the race against sync of an individual snapshot resource, or someone intentionally deletes the configmap, the data map could be nil and cause a crash.

While some implementations may support it, it appears that most don't,
and some may in fact return an error if it is requested.
We already stat the object to get the metadata anyway, so this was
unnecessary if harmless on most implementations.

Removing this in 002e6c43ee regressed

Write the extra metadata both locally and to S3. These files are placed such that they will not be used by older versions of K3s that do not make use of them.
