[FLINK-7530][flip6] Migrate TaskManagerMetricsHandler to new
RestServerEndpoint
## What is the purpose of the change
*FLIP-6 efforts: Migrating HTTP handlers*
## Brief change log
- Migrate logic from
`org.apache.flink.runtime.rest.handler.legacy.metrics.TaskManagerMetricsHandler
to` new handler.
- Add new handler to `DispatcherRestEndpoint`.
## Verifying this change
- *Added unit tests for all new classes and modified existing classes
except for DispatcherRestEndpoint.*
- *Manually deployed a job locally and verified with `curl` that
TaskManager metrics can be queried in FLIP-6 standalone mode. Note that the
task manager ids exposed by the WebUI in FLIP-6 mode are currently broken
(https://issues.apache.org/jira/browse/FLINK-8150). I had to obtain valid ids
by setting a breakpoint in `ResourceManager`*
