CLOUDSTACK-10073: KVM host RAM overprovisioning (#2266)
Commit enables a new feature for KVM hypervisor which purpose is to increase
virtually amount of RAM available beyond the actual limit.
There is a new parameter in agent.properties: host.overcommit.mem.mb which
enables adding specified amount of RAM to actually available. It is necessary
to utilize KSM and ZSwap features which extend RAM with deduplication and
compression.
