    [FLINK-8080][metrics] Remove need for "metrics.reporters" config key

    ## What is the purpose of the change
    This PR simplifies the reporter configuration by no longer requiring users to explicitly
set a list of reporter names via `metrics.reporters`. Instead, the names are automatically
determined based on `metrics.reporter.<name>.<option>` keys found in the configuration.
    ## Brief change log
    * modify reporter configuration parsing to detect reporter names
    * deprecate `MetricOptions.REPORTERS_LIST`
      * remove all usages
      * remove all references from documentation
    ## Verifying this change
    This change is already covered by existing tests in the various reporter modules that
configure a reporter.
    See all tests where `MetricOptions.REPORTERS_LIST` was removed.

>             Project: Flink
>          Issue Type: Improvement
>          Components: Configuration, Metrics
>            Reporter: Chesnay Schepler
>            Assignee: Chesnay Schepler
>            Priority: Trivial
>             Fix For: 1.5.0
> Currently, in order to use a reporter one must configure something like this:
> {code}
> metrics.reporters: jmx
> metrics.reporter.jmx.class: ...
> {code}
> It would be neat if users did not have to set {{metrics.reporters}}. We can accomplish
this by a scanning the configuration for configuration keys starting with {{metrics.reporter.}}
and using the next word as a reporter name.
