    Description

      Patch contains the following proposed fixes and improvements:

      Fix template matching in affected facets accounting (when the == and != operators are used, the string to the right of the operator is considered a pattern);

      Reduce failover duration done by facet_failover(): Long failover duration needs increasing of ldlm_enqueue_min to avoid evictions with striped objects, so let's do node reboot and mount on failover node in parallel.

      Make wait_clients_import_state() working with a facet list;
