Brad Davidson 095e34d816 Fix issues with defragment and alarm clear on etcd startup
* Use clientv3.NewCtxClient instead of New to avoid automatic retry of all RPCs
* Only timeout status requests; allow defrag and alarm clear requests to run to completion.
* Only clear alarms on the local cluster member, not ALL cluster members

Brad Davidson 0826ebc142 Fix race condition when multiple nodes reconcile S3 snapshots
Don't delete s3 etcdsnapshotfiles if they are missing from s3 but less than a minute old, its possible the other node just finished uploading it and the object key has not yet become visible.

Brad Davidson c36db53e54 Add etcd s3 config secret implementation
* 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

Brad Davidson aa4794b372 Replace 1-weight semaphore on snapshots with simple mutex
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.
