#
# This test suite checks the following statements:
#   - CREATE INSTANCE <instance_name> [option1[=option1_value], ...];
#   - DROP INSTANCE <instance_name>;
#
# For CREATE INSTANCE we check that:
#   - CREATE INSTANCE succeeds for non-existing instance;
#   - CREATE INSTANCE fails for existing instance;
#   - CREATE INSTANCE can get additional options with and w/o values;
#   - CREATE INSTANCE parses options and handles grammar errors correctly.
#     Check that strings with spaces are handled correctly, unknown (for
#     mysqld) options should also be handled;
#   - CREATE INSTANCE updates both config file and internal configuration cache;
#   - CREATE INSTANCE allows to create instances only with properly formed
#     names (mysqld*);
#
# For DROP INSTANCE we check that:
#   - DROP INSTANCE succeeds for existing instance;
#   - DROP INSTANCE fails for non-existing instance;
#   - DROP INSTANCE fails for active instance.
#   - DROP INSTANCE updates both config file and internal configuration cache;
