Set swap size to 4G for c8 jobs
Tempest is failing randomly with different reasons
as mentioned in the bug, updating swap size those
issues are not seen.
Before [1] default swap size used to be 8GB but was dropped
to 1G so need to configure it in required job itself.
Did couple of tests in [2] and with 4GB+ swap jobs are
running green. On investigation found that with qemu-5
both Ubuntu and CentOS jobs have memory crunch, currently
Ubuntu jobs are not impacted as they are running with
qemu-4.
