Fixes eventlet monotonic clock issue
The eventlet clock must be patched with the monotonic clock in order to avoid issues caused by drifs of system time. This is done in nova/__init__.py, but if compute-hyperv is installed after nova, compute-hyperv will overwrite that file. Closes-Bug: #1749088 Change-Id: I0d32406a65d1f4d57435766d41a0f1c1efba2782
