[FLINK-8370][REST] Port AggregatingMetricsHandler to flip6 ## What is the purpose of the change This PR ports the `AggregatingMetricsHandler` classes to flip6. Additionally this PR contains 2 minor changes: * the `MessageParameter` constructor is now `protected` * the converter methods of `QueryParameters` may now also throw `ConversionExceptions` like their `PathParamater` counter-part ## Brief change log * the `MessageParameter` constructor is now `protected` * the converter methods of `QueryParameters` may now also throw `ConversionExceptions` like their `PathParamater` counter-part * port `AggregatingMetricsHandler` to flip6 * duplicate `DoubleAccumulator` class * define headers, various parameters and response bodies * define handlers * conceptually they work like the legacy versions, but I had to beef up the aggregation factories a bit as the existing approach wasn't compatible with an actual constructor * add handlers to WebMonitorEndpoint ## Verifying this change This change added tests and can be verified as follows: * run tests extending `AggregatingMetricsHandlerTestBase`. ## Does this pull request potentially affect one of the following parts: - Dependencies (does it add or upgrade a dependency): (no) - The public API, i.e., is any changed class annotated with `@Public(Evolving)`: (no) - The serializers: (no) - The runtime per-record code paths (performance sensitive): (no) - Anything that affects deployment or recovery: JobManager (and its components), Checkpointing, Yarn/Mesos, ZooKeeper: (no) - The S3 file system connector: (no) ## Documentation - Does this pull request introduce a new feature?
