maas: region: credentials workaround, force sync

Workaround the issues described in [1], stating that salt-formula-maas
package cannot set an autogenerated PostgreSQL password, respectively
the known error thrown during initial setup.

FIXME: These should be reverted later, after fixing the MaaS password
update and initial artifact sync in the salt formula / scripts.

+Subject: [PATCH] maas: region: skip credentials update
+
+Password update for maas psql database breaks ulterior acesses
+to maas-region syncdb.
+For now, limit regiond.conf changes to maas_url, and skip
+updating credentials.

+Subject: [PATCH] maas: region: force artifact download
+
+MaaS configuration fails until all required artifacts are in place,
+including bootloaders and target images.
+
+Hack around this by forcing an explicit artifact sync.
+
+NOTE: This is probably achievable through existing maas salt custom
+module (py) and/or minor rework on that.
+This fixup should be temporary at best.
