[system_tests] Tests ceph_multinode_compact_ostf failed according wrong configuration

Test ceph_multinode_compact_ostf failed.
Tests assume that deploy enviroment with next properties:
 Scenario:
            1. Create cluster
            2. Add 1 node with controller and ceph OSD roles
            3. Add 1 node with compute and ceph OSD roles
            4. Deploy the cluster
            5. Check ceph status
            6. Run OSTF

As we can see there is 2 node (slaves) each of then has 1 cpu and 1024 memory
see setting.py
    "slave_node_memory": os.environ.get("SLAVE_NODE_MEMORY", 1024),
    "slave_node_cpu": os.environ.get("SLAVE_NODE_CPU", 1),

to get instance active we need for compute as minimum 700 MB and 1 cpu (but compute share this resource(1-1024) with ceph osd)

As result all instances go to ERROR state
