Add a filter by name to Metrics REST API

Filter by name is accessed by putting an "ids" parameter in the
query string passed to the REST API.  Here are some examples:

/wm/onos/metrics
Fetches all metrics known by the system

/wm/onos/metrics?ids=timer1
Fetches just the metric named "timer1"

/wm/onos/metrics?ids=timer1,gauge2
Fetches the metric named "timer1" and the metric name "gauge2

Note that the object returned by this query is always the Meteric Resource Object.
If a filter is applied, the values in the structure will be filtered, but the
object returned is the same."
