enhancing target host clean script

[Serguei Bezverkhi]

Kolla deployment creates /etc/kolla folder on a target host with multiple configuration files. In some scenarios, the presence of these files prevent successful deployment of certain services especially when their configuration parameters have been changed on the deployment host.
Removing /etc/kolla on a target host will prevent hitting such situations.

[Steven Dake (sdake)]

lets figure out what stuf doesn't get cleaned up.

I know /etc/fstab isn't cleaned of ceph
it seems like the heka configuration isn't recopied if it has changes.

The Ceph part is covered with bug https://bugs.launchpad.net/kolla/+bug/1562991

    in /etc/kolla directory which contains the build
    configuration for building images.
    This should be preserved.
