SQL

Add support for the SHOW CREATE CLUSTER command, which returns the DDL statement used to create a cluster.

SHOW CREATE CLUSTER c;

    name          |    create_sql
------------------+--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
 c                | CREATE CLUSTER "c" (DISK = false, INTROSPECTION DEBUGGING = false, INTROSPECTION INTERVAL = INTERVAL '00:00:01', MANAGED = true, REPLICATION FACTOR = 1, SIZE = '100cc', SCHEDULE = MANUAL)

Bug fixes and other improvements

Add the mz_catalog_unstable and mz_introspection system schemas to the system catalog, in support of the ongoing migration of unstable and replica introspection relations from the mz_internal system schema into dedicated schemas.
Add introspection_debugging and introspection_interval to the mz_clusters system catalog table. These columns are useful for feature development.
Fix a bug in the MySQL source that unecessarily enforced the replica_preserve_commit_order configuration parameter when connecting to a primary server for replication. This configuration parameter is only required when connecting to a MySQL read-replica.
