Broken endpoint URLs

Wonder if this is related to https://bugs.launchpad.net/charms/+source/keystone/+bug/1385162

The issue might be in the resolve_address function in charm-helpers:

def resolve_address(endpoint_type=PUBLIC):
    """Return unit address depending on net config.

    If unit is clustered with vip(s) and has net splits defined, return vip on
    correct network. If clustered with no nets defined, return primary vip.

    If not clustered, return unit address ensuring address is on configured net
    split if one is configured.

    :param endpoint_type: Network endpoing type
    """
    resolved_address = None
    vips = config('vip')
    if vips:
        vips = vips.split()

    net_type = ADDRESS_MAP[endpoint_type]['config']
    net_addr = config(net_type)
    net_fallback = ADDRESS_MAP[endpoint_type]['fallback']
    clustered = is_clustered()
    if clustered:
        if not net_addr:
            # If no net-splits defined, we expect a single vip
            resolved_address = vips[0]

However I would still expect that to return a single VIP, not all of them.

But that's from next; in the stable charm:

def resolve_address(endpoint_type=PUBLIC):
    resolved_address = None
    if is_clustered():
        if config(_address_map[endpoint_type]['config']) is None:
            # Assume vip is simple and pass back directly
            resolved_address = config('vip')

So this should get a bit better once we release 15.01.
