This is motivated by the fact that:
* the ntp/chrony package is already a dependency of the ceph-mon/osd
package
* NTP will be managed by operators through the NTP charm
It is thus useless to keep that package mentioned here.

Helper functions for the ceph charms. This library has shared functionality that is used in the ceph-mon, ceph-osd and ceph
charms. Anything that needs to be shared across the ceph charms should live here.
