This patch adds two new FIPS enabled jobs to determine if there are any
issues when FIPS is enabled.
Because the FIPS jobs currently run on centos, code is added to the
test setup script to set up the databases correctly. Also had
to increase the swap space on the nodes; see [0] for an explanation.
