Enable passing the certificate authority on the relation in order to
enable TLS communication to the MySQL DB.
In order to enable MySQL to use TLS for client connections all that
is required is the CA certificate. A certificate and key may be used
for client certificate authentication. However, since almost all
deployments will not use certificate authentication, focusing on the CA as SSL
data complete makes sense.

Prior to this change there was no way to specify a port for mysql

Check the allowed_units list past back by the db before raising the
'available' state to ensure charms do not try to connect to the db
before they are allowed.

If there are still HA units in the relation when a single unit departs
re-evaluate state. If it is the last unit, unset all relation states.
Handle the case juju remove-relation and juju add-relation.

Partial-Bug: #1800730
Instead of relying on the user of the interface to set the correct
hostname parameter when configuring database access request,
automatically determine the correct hostname using:
1) In Juju >= 2.0, using the network space binding of the
named relation.
2) In Juju < 2.0, using the units private-address.
The hostname relation value can be overridden using the hostname
parameter of the configure method.
