# Multi master member state change test
# This test serves the purpose of evaluating the state changes a member can
# undergo.
#
# The state changes tested are:
# 1) Single member group
#    Member 1: Offline =>  Online
# 2) Member joining into existing group
#    Member 2: Offline => Recovering => Online
# 3) Member leaving (after adding another member to guarantee quorum):
#    Member 3: Online => Offline
# 4) Clean up.
