fix: add kubernetes client QPS and Burst config

[lobshunter]

This PR adds kubernetes client-go QPS and Burst configuration. Default value will be used if not configured.

Default settting only allows QPS=5, it might cause a lot of warnings like:

Waited for 1.194248853s due to client-side throttling, not priority and fairness

This can be a solution to #159.

What do you think @mustafaakin-atl?

This PR looks like it would solve our issues with throttling -- hoping to see it merged soon!
