Code Issues Proposed changes

Dual Stack VIPs

Browse Source 
Enable dual stack IPv4 and IPv6 VIPs on the same interface.
HAProxy always listens on both IPv4 and IPv6 allowing connectivity
on either protocol.

charm-helpers sync for HAProxy template changes.

requires the key to be passed directly, whereas this function passes an
