[16/52] [abbrv] flink git commit: [FLINK-4851] [rm] Introduce
FatalErrorHandler and MetricRegistry to RM
[FLINK-4851] [rm] Introduce FatalErrorHandler and MetricRegistry to RM
This PR introduces a FatalErrorHandler and the MetricRegistry to the RM. The FatalErrorHandler is used to handle fatal errors. Additionally, the PR adds the MetricRegistry to the RM which can be used
to register metrics.
Apart from these changes the PR restructures the code of the RM a little bit and fixes some
blocking operations.
The PR also moves the TestingFatalErrorHandler into the util package of flink-runtime test. That
it is usable across multiple tests.
Introduce ResourceManagerRunner to handle errors in the ResourceManager
This closes #2655.
