all: add connection.multi-connect property for wildcard profiles

Add a new option that allows to activate a profile multiple times
(at the same time). Previoulsy, all profiles were implicitly
NM_SETTING_CONNECTION_MULTI_CONNECT_SINGLE, meaning, that activating
a profile that is already active will deactivate it first.

This will make more sense, as we also add more match-options how
profiles can be restricted to particular devices. We already have
connection.type, connection.interface-name, and (ethernet|wifi).mac-address
to restrict a profile to particular devices. For example, it is however
not possible to specify a wildcard like "eth*" to match a profile to
a set of devices by interface-name. That is another missing feature,
and once we extend the matching capabilities, it makes more sense to
activate a profile multiple times.

See also https://bugzilla.redhat.com/show_bug.cgi?id=997998, which
previously changed that a connection is restricted to a single activation
at a time. This work relaxes that again.

This only adds the new property, it is not used nor implemented yet.
