This commit brings necessary configuration and container start-up
options to use two popular backends for backup - nfs and swift.
Both drivers support incremental backups and should work with any
cinder volume backend.

When configuring kolla with

 - kolla_enable_tls_external: "yes"

ceilometer service credential defaults to publicURL.

Ceilometer should work with the internal interface (v3 API Identity syntax):

.....
[service_credentials]
interface = internal

PyMySQL is prefered to PythonMySQL for Sqlalchemy, as it provides
python3 support and is actively maintained, and is therefore the
currently recommended lib for db connections.
 * https://wiki.openstack.org/wiki/PyMySQL_evaluation

Kolla currently uses PyMySQL for all connections bar Barbican
(which works fine with PyMySQL): once this commit is merged it will
be possible to remove the PythonMySQL libs, and mysql libs for kolla
images (except kolla-toolbox).

Closes-Bug: #1629893

If an operator wants to deploy a single node (e.g. add an additional
compute), they may want to use the --limit feature of Ansible to avoid
waiting for every play across every node.

The problem with this is that --limit will gather facts for that node
only, causing template errors such as the infamous ('dict object' has no
attribute u'ansible_eth0'").

Ansible has catered to this problem to an extent with it's
"delegate_facts" mechanism. The only problem is that in the default 'all
nodes' case, we end up with a storm of SSHs as each node SSHs to every
other. I'm solving this with a separate task to only use this mechanism
when a subset of nodes has been specified (see ansible_play_batch).

Using the `when` conditional on a `with_` loop gets evaluated on each
loop iteration and will not skip a task entirely. Use the `skip`
attribute to ignore errors in this scenario but only `skip` when
`enable_cinder_backend_nfs` is not enabled. If it is enabled the
`nfs_shares` file should be required and this task should fail if it
does not exist.
