#
# Error in the election process that prevent its progress shall
# make the server leave the group (if configured to) as its configuration
# may have deviated from the group.
#
# Test:
# 0. This test requires three servers
# 1. Server1 start, bootstrap the group
# 2. Start server2 and server3
# 3. Fake a stopped applier on server2
# 4. Set server2 weight higher to be new primary server
# 5. Stop primary member that will force election from another member
# 6. Server2 will fail (applier thread stopped) and leave the group
# 7. Server3 is the new primary
# 8. Confirm server2 is on ERROR state
# 9. Cleanup
