For share drivers that do support handling of share servers may be useful case
when used different share servers but with shared network. This new plugin
allows to use some specific network and subnet from Neutron for all share
servers within some back-end.
Add two configuration options ('neutron_net_id', 'neutron_subnet_id'), that can
be defined as all other opts for network plugins. For each back-end can be
defined it's own pair of these two options if this new plugin is enabled.
New configuration opts accept only IDs and provided subnet should be assigned
to provided network else error will be raised on start of manila-share service.
If provided share-network has values for net and subnet, they will be
redefined.
Implements blueprint neutron-single-network-plugin
