More flexible version skew between client and server

This release of kube-applier allows a 1 version skew between client and server in either direction

Log Level

This release introduces a new, optional env var to set the log level of the kubectl commands executed by kube-applier

Quick Run

This release introduces the "quick run" feature. Quick runs (triggered by a new commit) apply only the files modified since the last commit, and are handled separately and concurrently alongside full runs (triggered by the "force run" button and at periodic intervals).

Various tests have been added and rewritten (notably, the scheduler and metrics components now have tests).
