Allows for specifying CPUs and RAM for VMs in virtual deployments
Changes Include: - All VMs (undercloud and overcloud) now default to 4 vCPUs - Allow specifying number of vCPUs per overcloud VM with --virtual-cpus <number> - Allow specifying amount of RAM per overcloud VM with --virtual-ram <size in GB> - Undercloud now uses 10GiB of RAM to avoid OOM JIRA: APEX-111 Change-Id: I541c669b869a90134bc8af25786fe3b1a557376b Signed-off-by: Tim Rozet <trozet@redhat.com>
