no ability for vault:lb-provider to create an octavia LB for Vault VIP

[Jeff Hillman]

charms stable/latest

Currently the *-integrator charms only work with Azure to provide a VIP for loadbalancer aware applicatoins, such as vault. The openstack-integrator charm should also provide this functionality so that clustered vaults can existing in an openstack substrate.

the current work around is to manually create an openstack port, assign a FIP (when necessary), allow all vault units to access that port, then set the VIP in the vault charm option.
