Add more logs

[srgothi92]

Description
Currently controller logs are very limited even with the debug flag on. Due to this it's hard to understand what is happening in between the labels received and labels posted. Additional logs needs to be added before starting each new step like update, cordon, drain, verify update etc. to better understand update progression and debug issues.

Current logs:

This should be fixed in the latest Update Operator release, 0.2.0. We've surfaced considerably more logs, as well as Prometheus metrics. These should make it easier to debug issues.
