summary: Ensure that the openvswitch interface works.
details: |
The openvswitch interface allows to task to the openvswitch socket (rw mode).
A snap which defines a openvswitch plug must be shown in the interfaces list.
The plug must not be autoconnected on install and, as usual, must be able to be
reconnected.
A snap declaring a plug on this interface must be able to do all the operations that
are carried through the socket, in this test we exercise bridge and port creation,
list and deletion.
