bump guest ram to prevent kernel panics
one observation we had in down stream ci is
sometimes the cirros 0.6.2 image appared to
crash when using 128MB of ram.
upstream we have been dealing with semi random
kernel panics which are losely corralated with
cinder volume usage.
Recently we optimisted the devstack jobs by using zswap
this has reduced memory pressure in the jobs.
This patch increase the ram allocated to a flavor
to see if we can afford that with the current conncurnace
level in an attempt to reduce kernel panics.
Two new parmaters are added to allow jobs or users
to set the desired ram size.
TEMPEST_FLAVOR_RAM=${TEMPEST_FLAVOR_RAM:-192}
