HA: update bundle creation to be compatible with newest pcs

The latest version of pcs [1] makes it mandatory to specify the
container type when creating a pacemaker bundle resource. Update
the resource creation statement accordingly.

This change is backward compatible with the pcs version in RDO,
because the pcs argument already exists in this version, it is just
optional.
