Introduce ShardState Enum + Slight Cleanup SnapshotsInProgress (#41940) (#42573) 

* Added separate enum for the state of each shard, it was really
confusing that we used the same enum for the state of the snapshot
overall and the state of each individual shard
   * relates https://github.com/elastic/elasticsearch/pull/40943#issuecomment-488664150
* Shortened some obvious spots in equals method and saved a few lines
via `computeIfAbsent` to make up for adding 50 new lines to this class
