Check if VIP or dns-ha is set to determine if the unit expects to be in HA. This is less racey that just checking for the ha relation. Wait until clustered to run the client relation hooks. This fixes bugs where client charms receive the private-address rather than the VIP on initial client relations. Charmhelper sync.
