[FLINK-4535] [cluster management] resourceManager process the registration
from TaskExecutor
This pull request is to implement ResourceManager registration with
TaskExecutor, which including:
1. Check whether input resourceManagerLeaderId is as same as the current
leadershipSessionId of resourceManager. If not, it means that maybe two or more
resourceManager exists at the same time, and current resourceManager is not the
proper rm. so it rejects or ignores the registration.
2. Check whether exists a valid taskExecutor at the giving address by
connecting to the address. Reject the registration from invalid address. (which
is hidden in the connect method)
3. Keep resourceID and taskExecutorGateway mapping relationships, And
optionally keep resourceID and container mapping relationships in yarn mode.
4. Send registration successful ack to the taskExecutor.
Main difference are 3 points:
1. Add UnmatchedLeaderSessionIDException to specify that received leader
session ID is not as same as expected.
2. Change registerTaskExecutor method of ResourceManager
3. Add a test class for ResourceManager
