>             Project: Flink
>          Issue Type: Improvement
>          Components: Runtime / Coordination, Runtime / Metrics
>    Affects Versions: 1.10.0
>            Reporter: Till Rohrmann
>            Assignee: Till Rohrmann
>            Priority: Major
>              Labels: pull-request-available
>             Fix For: 1.10.0
>          Time Spent: 10m
>  Remaining Estimate: 0h
> At the moment, we use the {{JobManagerMetricGroup}} to not only register {{Dispatcher}}
specific metrics but also process specific metrics such as CPU, threads, memory, etc. Due
to this fact, it is not possible to close the {{JobManagerMetricGroup}} when the life time
of the {{Dispatcher}} terminates. In order to do this, I suggest to introduce a new {{ProcessMetricGroup}}
which is used to register the process specific metrics. 
> In order to guarantee backwards compatibility, I suggest to use the same scope format
as {{SCOPE_NAMING_JM}} and then appending {{.Status}}.
