(POOLER-140) Ensure a VM is alive at checkout
This commit duplicates the vm_ready? check to the API layer to allow for API to validate that a VM is alive at checkout. Without this change API relies upon the checks in pool_manager validating pools. This change should allow for additional insight into whether a machine is in a ready state and resopnding at checkout time.
