PE-19888 Add workaround for 2016.1.1 console service status check error

During installation, a classifier-service check is done in beaker-pe
to make sure console service is up and running. The classifier status
service at the default detail level is broken in 2016.1.1 (PE-14857)
and returns an error and state "unknown". The workaround is to query
the classifier-service at 'critical' level and check for the console
service status.
