[FLINK-5419] Make full TM metrics available through REST API
This PR fixes the full set of TaskManager metrics not being available
through the REST API. The issue was that multiple handlers were registered for
the same URL ("/taskmanagers/:taskmanagerid/metrics").
The relevant handlers are the ```TaskManagersHandler``` which provides a
subset of metrics to the WebInterface (basically what is displayed in the
metrics tab in the TM page) and the ```TaskManagerMetricsHandler``` which
provides full access to metrics.
The issue was fixed by making the metrics tab use the following URL:
"/taskmanagers/:taskmanagerid". This is in fact a reversal of a previous
change, which technically changed a public API.
While fixing this i found a bug in the ```TaskManagerMetricsHandler```; it
used the wrong constant to extract the TaskManagerID from the path ("tmid"
instead of "taskmanagerid")
