[NETCONF-346] modules-state conflict kills rest-connector-default-impl

Fri, 15 Mar 2019 22:22:35 +0000

Not sure if this belongs to Restconf or Netconf.

This Bug is very similar to ~~BGPCEP-596~~ except it happens much more frequently in 3node ~~all~~ jobs.
"Server is unhealthy" (which causes red dot in CSIT) is caused by a conflicting modification, which prevents config subsystem module instantiation.
