Enabling use of Metrics in Oak to simplify and improve stats collection (OAK-3654)

Hi Team,

As part of OAK-3654 (and on Ian Boston suggestion) I have been
prototyping an approach which enable use of very feature rich Metrics
library [1] within Oak. This introduces an optional dependency on
Metrics library and enable rich stats collection

These stats provide better insight in system performance compared to
our current TimeSeries based collection. Refer to [2] for the short
user guide on this library

Approach used ensures that Oak can work without this library and has
wider code does not depend on Metrics API. The integration can be
enabled via OSGi and hence pluggable. By default only TimeSeries based
data would be collected.

Kindly have a look at OAK-3654 and provide your inputs there!
