[submodule] Add docker-salt-formulas, ci/build.sh

- add new git submodule pointing to upstream docker build scripts;
- add patch extending Docker tags with an '-(arch)' suffix,
  aligning with OPNFV tagging requiremnts;
- add <ci/build.sh> wrapper for starting Docker builds;
- install build-specific distro package requirements, as well as
  pip-managed packages (e.g. pipenv);

+Subject: [PATCH] OPNFV tag convention alignment
+
+* (arch)- prefix Docker tags
+  Hacky implementation that only detects 'arm64', otherwise it will
+  default to 'amd64'.
+  Note that Docker arch notation uses 'arm64' instead of 'aarch64'.
+* Override Docker tag to align with OPNFV format
+* use Docker repository: opnfv/fuel
