minor cosmetic tweaks for 1.2.3

The changes are cosmetics to leave the docker repo
a bit more tidy for release.

The switch from openecom.org to onap.org is
functionally noop .conf files as both domain names are
supported.

The BRMS_DEPENDENCY_VERSION is noop as it will
be properly substituted by the underlying docker-install.sh
invocation during docker brmsgw container instantation
bringup.
