Keep chrony installed when purging a cluster

Chrony is mandatory on a ceph node but could be already present before installing Ceph. At Ceph uninstallation, we will keep it installed but this behavior can be changed by changing the "keep_chrony_installed" variable. Fixes: #239 Signed-off-by: Teoman ONAY <[email protected]>
