[stable-2.8] Disable the rabbitmq tests for now

The erlang-solutions repository is broken for Ubuntu18 (They did not
sign their repository metadata).  For now, disable the rabbitmq tests
which depend upon that.  I'll open a PR with a revert of this commit.
We can watch it to see when it passes in Ci to know that the
erlang-soutions repository has been fixed
(cherry picked from commit 5f47ab9)
