…ts into ICassandraManagementProxy and implement in both HTTP and JMX impls. (#1358)

Implement methods:
- getClusterName
- getLiveNodes
- clearSnapshot
- listSnapshots
- takeSnapshot

* Add stubbed polling of job details from the mgmt-api. This will not work without the actual client implementation

Implement using apiClient the triggerRepair, getJobDetails, scheduler as well as add a simple test to ensure the state is managed correctly

* Merge test files after the rebase

* Add a test to verify the behavior of the notifications polling

* Address comments

* Implement schema methods in the HttpManagementProxy (fixes #1344)

* Move HTTP repair implementation over to new V2 endpoint.

* Strip out Cassandra <3 repair methods and fix method signatures to always use newer ringrange.

* Fix tests.

* Remove tests for Cassandra <3.

* New cancelAllRepairs http method. More tests.

* Bump version of managment API client in pom.xml to bring in repair methods with correct Long integer type.

* Remove references to RunState NOT_EXISTING, since they cause spurious errors in tests and this state no longer exists.
* Remove references too JMX from ClusterFacade and make it more generic.

…e for each connectImpl call (#1413)

…epair().

Comment out test steps which rely on getPendingCompactions.
Comment out percent-repaired related test.

* Implement getPendingCompactions in the HttpManagementProxy

Since metrics are now exposed on a different port than the mgmt-api itself, this required to go through the HttpMetricsProxy which got partially implemented for that need.
It is now able to pull metrics from the metrics endpoint and parse it into GenericMetrics.

* Put a hook in the docker container's cassandra-reaper.yml so that the HTTP management proxy can be enabled via environent variable, instead of only through the config file.

* Update management API client and remove references to notifications in v2 repair requests.
