# Check mysqladmin output to test group_replication variable's values.
# Test :
# 0. This test requires 2 servers which should be in group replication
# 1. Bring up the group replication with 2 servers
# 2. Use myqladmin executable and dump all the variables to a file
# 3. Using perl script go through the dumped file and print all the
