[pve-devel] [RFC manager 2/5] api: ceph: create mon: handle ms_bind_ipv* options more generally

[Fabian Ebner]

mostly relevant to prepare support for IPv4/IPv6 dual stack mode as a special
case of the planned support for mutliple public networks.

As before, only set the false value when we are dealing with the first address,
but also be explicit about the IPv4 case as the defaults might change in the
future.

Then, when an address of a different type comes along later, set the relevant
bind option to true.
