    Set bigger swap in the functional and fullstack jobs
    
    As we are hitting some memory limits (again) in functional tests
    job, lets configure 8GB of swap in all functional and fullstack jobs.
    
    Before that patch swap was configured to 4GB only in the FIPS jobs. Now
    it will be set to 8GB in all functional and fullstack jobs.

Title:
  Functional tests hits oom-killer which is causing job failures

Status in neutron:
  Fix Released

Bug description:
  Failure example
  https://storage.bhs.cloud.ovh.net/v1/AUTH_dcaab5e32b234d56b626f72581e3644c/zuul_opendev_logs_a75/833620/4/check/neutron-
  functional-with-uwsgi/a75e59b/testr_results.html

  It seems that oom-killer is killing test runner and that is causing
  job failure:
