If a bridge does not have a fail mode set, it returns nothing, i.e.
empty string.
This causes a failure when doing the want vs have compare in plays
where the fail-mode is missing, as we compare "" vs None respectively.
If a bridge does not have external_ids, ovs-vsctl returns '{}'.
This causes issues on the current want vs have comparison in cases
where the play does not define external_ids, as the comparison
is None vs '{}'.
Ok, so for openvswitch_db in particular we just return one command
but in the sake of consistency and code re-use, let's return a list
of "commands", even if it's just one.
The openvswitch_db module uses the ovs-vsctl binary to
address changes.
On other network modules we follow the pattern of returning 'commands'
as part of the result, containing the commands run on the target device.
Follow that for code consistency and maintenance.
Also, adding state param, which allows to add/remove keys on columns.
