Description

Although it's possible to prevent initiating new scrubs, we don't have a facility for terminating already on-going ones:
http://lists.ceph.com/pipermail/ceph-users-ceph.com/2014-April/038488.html.

The problem pops up during maintenance of large deployments. Their huge size translates into small chance that all PGs are active+clean which affects e.g. upgrades. The ultimate outcome is unnecessary prolongation of maintenance windows.
The issue has been recently risen by Sergii Golovatiuk.

We may be able to easily terminate scrubbing in between chunks if the noscrub/nodeep-scrub get set.

I will test this.
