Review request for cloudstack and Chip Childers.


updated summary to reflect adjustment in patch

Summary (updated)

Don't do KVM heartbeat on secondary storage sources, primary only


the KVM HA runner uses any NFS secondary storage resource available to a host to store it's
HA data. This causes template deletes to fail because it cannot delete KVMHA, which is a directory
that is not empty. So if KVMHA directory is found, delete it's contents before trying to delete

This addresses bug CLOUDSTACK-2173.

diff revision 2 was tested with a new 4.1 zone deployment. Verified bug was reproducable with
4.1 HEAD, applied patch, ran through adding two NFS primary storages, verified KVM heartbeat
was working on them, then ran various secondary storage operations (register template, download
volume, take snapshot) and verified that they worked, and that KVM heartbeat operations were
NOT acting on them.
