Allow unsharing a network used as gateway/floatingip

If network has ports that connect it as gateway to another network, such
as an external network, or "floating ip" ports it should still be
possible to "unshare" it since these ports represent usage of the
network as an external network, not as a VM data network.

Fix enums usage for postgres in migrations

For downgrade with postgres it is not enough to just drop_table if
table contains enums. The enums should be removed separately after
deleting the table.

Also, if a migration uses an existing enum then postgresql needs some
specific code to re-use this enum.

Use correct section for log message if interface_driver import fails

If import of interface_driver in namespace_driver fails then message for
logger raises exception because of taking interface_driver from haproxy

Use storage engine when creating tables in migrations

Although __table_args__ is set correctly in the base model, existing
migration scripts were not generated with the mysql_engine option in
the alembic output, likely due to:

https://bitbucket.org/zzzeek/alembic/issue/110/

This adds the mysql_engine option to each table creation operation.

Fix-DVR Gateway clear doesn't delete csnat port

When a gateway is set to a distributed router,
the router checks for the interfaces associated
with the router and based on the number of
interfaces the router creates "csnat" interface
ports that would be used by the SNAT service in
the Service Node.

When a gateway is cleared, the plugin should
delete the "csnat" interface ports. In the
current code, it is deleting the port and
re-creating the port with a different id.

A check need to be made before it creates a new
port to make sure that the router has a valid
gateway port.

This is a bug and this patch fixes this issue.

When agent_mode=dvr only distributed routers should be

Make ML2 ensure_dvr_port_binding more robust

There is a remote chance that this operation may
be prone to DB integrity errors, in case the binding
is attempted on the same port twice.

Ideally getter methods should not create, but this
is a common Neutron (anti)-pattern that would be
difficult to eradicate (at least in a single patch);
so for now let's make this code more defensive.
