L23network related fixes:

* l23network module initialization for granular deployment
* wrong bridge type while creating integration and tun bridge.
* bug/1446187

Note: After refactoring L23network module default provider
for bridges was changed from 'ovs' to 'lnx', but Neutron
requires 'ovs' bridges in any way.
Neutron no more need for creating br-int and br-tun
(upstream-bug: https://bugs.launchpad.net/puppet-neutron/+bug/1436422)
