[one-users] Making scheduler allocation aware

[Rangababu Chakravarthula]

Javier

We saw that VM's were being deployed to the host where the allocated memory
of all the VM's was higher than the available memory on the host.

We think OpenNebula is executing free command on the host to determine if
there is any room and since free would always return the actual memory that
is being consumed and not the allocated, opennebula would push the new jobs
to the host.

That's the reason we want OpenNebula to be aware of memory allocated to the
VM's on the host.
