Version-Release number of selected component (if applicable):

How reproducible: every time

Steps to Reproduce:
1. Deploy foreman server
2. Add host to Neutron controller host group
3. Add host to Neutron networker host group, specifying internal and external bridge parameters
4. Run puppet agent -tv
5. Run ovs-vsctl show to check whether 

Actual results:
Bridge "br-p3p1"
        Port "phy-br-p3p1"
            Interface "phy-br-p3p1"
        Port "br-p3p1"
            Interface "br-p3p1"
                type: internal

Expected results:
Bridge "br-p3p1"
        Port "p3p1"
            Interface "p3p1"
        Port "phy-br-p3p1"
            Interface "phy-br-p3p1"
        Port "br-p3p1"
            Interface "br-p3p1"
                type: internal
