#
# Check the options-management commands:
#  - UNSET;
#  - FLUSH INSTANCES;
#
# Let's test the commands on the option 'server_id'. It's expected that
# originally the instances have the following server ids:
#  - mysqld1: 1
#  - mysqld2: 2
#
# The test case:
#
#  1. UNSET <instance_id>.server_id;
#
#   Do the step for both instances.
#
#   1.1. check that the configuration file has been updated (i.e.  does not
#     contain 'server_id=' line for the instance);
#   1.2. (for mysqld1) check that the running instance has not been affected:
#     connect to the instance and check that 'SHOW VARIABLES LIKE 'server_id''
#     returns non-zero value;
#   1.3. check that internal cache of Instance Manager is not affected (i.e.
#     SHOW INSTANCE OPTIONS <instance> contains non-zero value for server_id);
#
#  2. FLUSH INSTANCES;
#
#   Do the step for both instances.
#
#   2.1. check that the configuration file has not been updated (i.e.  does not
#     contain 'server_id=' for the instance);
#   2.2. (for mysqld1) check that the running instance has not been affected:
#     connect to the instance and check that 'SHOW VARIABLES LIKE 'server_id''
#     returns non-zero value;
#   2.3. check that internal cache of Instance Manager has been updated (i.e.
#     SHOW INSTANCE OPTIONS <instance> does not contain 'server_id=' line).
