Sanket SudakeandGitHub 154fe0d447 Retrieve pod metrics only if metrics server is running and Go lint fixes (#2094)
* Retrieve pod metrics only if metrics server is running

Currently we query pod metrics every 30 sec which floods executor logs,
added check which confirms if metrics server is running then only we start
querying pod metrics for identifying CPU utilization.
