[FLINK-7805][flip6] Add HA capabilities to YarnResourceManager
## What is the purpose of the change
*Recover previously running containers after a restart of the
ApplicationMaster.
This is a port of a feature that was already implemented prior to FLIP-6.*
cc: @tillrohrmann
## Brief change log
- *Extract `RegisterApplicationMasterResponseReflector` class into
separate file.*
- *Use `RegisterApplicationMasterResponseReflector` from within
`YarnResourceManager`*
## Verifying this change
This change added tests and can be verified as follows:
- *Added unit tests for `RegisterApplicationMasterResponseReflector`*
- *Manually deployed a cluster on YARN with HA enabled. Submitted a job,
and killed the master several times. Verified that the right log messages were
generated ("Recovered X containers from previous attempts"), and that the
taskmanager resource ids remained the same.*
