temp freeze releng version for stable/danube workaround

releng doesn't have a branch, so we need to freeze
the releng version.

There is an issue with releng fetch_os_creds.sh change

/home/opnfv/repos/releng/utils/fetch_os_creds.sh: line 75: BRANCH:
unbound variable

So we need to revert back to commit before this change
