Description

Currently we capture minimal metrics in Sidecar, through this patch we want to improve observability in Sidecar.

For this we want to record more metrics in Sidecar with Dropwizard. Introduce setup changes needed for capturing sidecar metrics through Dropwizard. 

Some of the metric kinds we will capture through this patch are, HTTP metrics like number of requests created per route, response time taken endpoint wise. Capture metrics per Cassandra instance maintained by Sidecar, such as, instance specific restore metrics, instance specific stream and upload metrics. We will also turn on registering, server route metrics emitted by Vert.x.
