Increase swap size to 4GB
This is to address issues in the cinder-plugin-ceph-tempest* jobs
where a significant number of builds are failing. Symptoms are a
lot of server fault errors, identity error: unexpected status
code 500, and db connection errors in the tempest log. On these
jobs, syslog shows multiple
oom_reaper: reaped process xxxxxxx (mysqld)
lines. Occasionally ceph-osd or ceph-mons are also reaped, but
it's pretty consistently mysqld.
Default swap size is currently 1G. Increase to 4GB was determined
experimentally. (See other patches on topic: increase-swap.)
