This controller only needs to run when using managed etcd, so move it in
with the rest of the etcd stuff. This change also modifies the
controller to only watch the Kubernetes service endpoint, instead of
watching all endpoints in the entire cluster.
Fixes an error message revealed by use of a newer grpc client in
Kubernetes 1.24, which logs an error when the Put to etcd failed because
kine doesn't support the etcd Put operation. The controller shouldn't
have been running without etcd in the first place.

Don't attempt to retrieve snapshot metadata configmap if the apiserver
isn't available. This could be triggered if the cron expression caused a
snapshot to be triggered before the apiserver is up.

Reuse the existing etcd library code to start up the temporary etcd
server for bootstrap reconcile. This allows us to do proper
health-checking of the datastore on startup, including handling of
alarms.

Several types contained redundant references to ControlRuntime data. Switch to consistently accessing this via config.Runtime instead.

* Fix URL pruning when joining an etcd member
Problem:
Existing member clientURLs were checked if they contain the joining
node's IP. In some edge cases this would prune valid URLs when the
joining IP is a substring match of the only existing member's IP.
Because of this, it was impossible to e.g. join 10.0.0.2 to an existing
node that has an IP of 10.0.0.2X or 10.0.0.2XX:
level=fatal msg="starting kubernetes: preparing server: start managed database:
joining etcd cluster: etcdclient: no available endpoints"
Solution:
Fixed by properly parsing the URLs and comparing the IPs for equality
instead of substring match.
