Increase verbosity of idler logs

[sthaha]

This does not fix the issue rather only adds more logging to idler so that we can analyse further why certain jenkins pods are not getting idled or woken up.

With these logs added we get the following information

• WARN idler disabled for user - skipping
• ERROR No user info found for namespace
• INFO Will send user to Idler due to active build
• INFO Evaluating conditions for user
• INFO active build started at has gone past completion action=idle component=build-condition
• INFO 30m0s has elapsed after jenkins last update at action=idle component=dc-condition
• INFO conditions/idle: true = build=true | DC=true | user=true name=user-name component=condition
