Subject: stop.sh: Issue only one SIGTERM to ceph processes
X-Git-Tag: v17.1.0~2413^2
X-Git-Url: http://git-server-git.apps.pok.os.sepia.ceph.com/?a=commitdiff_plain;h=5bd2a79daed8a77a3dedc9017518f8439b3591ad;p=ceph-ci.git

stop.sh: Issue only one SIGTERM to ceph processes

Modify stop procedure to issue only one SIGTERM.
Make loop to wait for processes to finish issue SIGCONT, a signal that does nothing.
