Clean up/Data Lifecycle of TssEncryptionKey in State

[derektriley]

Background
When a node id is not present in any of the active rosters or a candidate roster, the entry for that node id should be removed. This cleanup task should trigger any time there is a candidate or active roster state change.

Look at usages of WritableRosterStore::putCandidateRoster, putActiveRoster, removeRoster

Acceptance Criteria

• All code locations where active roster or candidate rosters are changed, need to check and trigger the cleanup task.
• Unit or Hapi Tests which verify the node id is removed from the TssEncrpytionKey map in state when the cleanup task occurs.
