Use rsync only if required

Only install rsync if export_nagios_definitions=True.
Do not use rsync if nagios_master is set but
export_nagios_definitions=False.

Previously if nagios_master is set, the charm behaves as if
export_nagios_definitions=True, however there are circumstances
requiring nagios_master to be set that do not require the rsync service
to be configured.

Remove version from charmcraft

Because there is no means to automate the version file in charmcraft, we
cannot expect auto builds using Launchpad recipes to get the version
file correct. For now, remove it from charmcraft.yaml to allow auto
builds in Launchpad to complete.

Add target-address to relation data

The Nagios charm makes use of a relation-data item named target-address,
which is used for connections from Nagios to the remote unit (NRPE).
If target-address is not set, Nagios then uses ingress-address, and if
that's not set, private-address. Both ingress-address and
private-address are automatically set by Juju, but updated by the nrpe
charm.

This change adds target-address to the relation data which is controlled
by the NRPE charm from the start, as under some circumstances the
ingress-address is overwritten by Juju.

Add python-openstackclient to functests

Since b46f13ef113e690493364dabc87821699626d8e6 in zaza, if running tests
on an OpenStack cloud provider, each bundle test concludes with a
cleanup routine that needs the python-openstackclient package in
requirements.txt for the tox environment, plus the OS_ environment vars
exported/passed through such that the Openstack client actually works.
If these are not set, the test fails on the first bundle cleanup and
does not continue to the remaining bundles.

Update check_netns.sh when id is included

Change defaults for check_swap_activity
