Rabbitmq app fails to start due to mnesia dir for plugins never cleaned up

How to reproduce:
1) Move master to node-2
2) wait for ostf ha passed
3) kill the node-2 and start count for failover time in a wait loop (wait for ostf ha passed)
4) power on node-2 and wait for it joined the rabbit cluster
5) repeat 1-4

Expected: the node-2 will always rejoin cluster after the step #4.

Actual: after few iterations, the node-2 ended up in bad state - cannot start rabbit app, even mnesia erasing doesn't help.

Here is the output of the manual check of the action start with OCF wrapper command:
ocf_handler_rabbitmq-server start 2>&1 | tee start

Here is the output of commands doing start rabbitmq-server in foreground and try to start_app:

# RABBITMQ_NODE_ONLY=1 su rabbitmq -s /bin/sh -c "/usr/sbin/rabbitmq-server" &
(note, beam starting as always and kernel module reported as running)
# rabbitmqctl start_app
Starting node 'rabbit@node-2' ...

BOOT FAILED

Error: {rabbit,failure_during_boot,{case_clause,{ok,[]}}}

This happens due to incomplete mnesia cleaning method in OCF script:
# rm -rf /var/lib/rabbitmq/mnesia/rabbit@node-2/
This is not enougth and may cause reported error!

Plugins dir should be erased as well:
# rm -rf /var/lib/rabbitmq/mnesia/rabbit@node-2-plugins-expand/

After that, If beam restarted, rabbit app will start w/o issues:
# rabbitmqctl start_app
Starting node 'rabbit@node-2' ...
...done.
