* return group memberships of entity during read
* Add implied group memberships to read response of entity
* distinguish between all, direct and inherited group IDs of an entity
* address review feedback
* address review feedback
* s/implied/inherited in tests
* Return role info for each role on pathRoleList
* Change roles -> key_info, only return key_type
* Do not initialize result map in parseRole, refactor ListResponseWithInfo
* Add role list test
This change makes these errors transient instead of permanent:
[ERROR] core: failed to acquire lock: error=etcdserver: requested lease not found
After this change, there can still be one of these errors when a
standby vault that lost its lease tries to become leader, but on the
next lock acquisition attempt a new session will be created. With this
new session, the standby will be able to become the leader.

* Add test for encrypt, decrypt and rotate on RSA keys
* Support exporting RSA keys
* Add sign and verify test steps
* Remove 'RSA' from PEM header
