# When a primary election is running, executing an action it will fail
#
# Test:
#   0. This test requires three servers
#   1. Start server1 and bootstrap group
#   2. Configure server2 with weight to be next primary
#   3. Lock table to block primary election
#   4. Start server3
#   5. Insert data to prevent server2 set read only and block on primary
#      election
#   6. Stop server1 and run primary election
#   7. Executing an action will fail, a primary election is running
#   8. Unlock table to primary election finish
#   9. Assert server2 is the new primary
#  10. Cleanup
