sql: add a SHOW TENANTS command

This command prints all available tenants and their status. To get the status for replication (c2c) tenants we need to get the job info. For example: ``` [email protected]:26257/defaultdb> show tenants; id | name | status -----+----------+---------------------------------------------------------------------- 1 | system | ACTIVE 2 | src | ACTIVE 3 | dest | REPLICATION PAUSED 4 | dest2 | REPLICATION UNKNOWN (succeeded) 6 | dest3 | REPLICATION UNKNOWN (job with ID 819888096954253313 does not exist) 11 | dest4 | ACTIVE 12 | dest5 | REPLICATING 13 | dest6 | INITIALIZING REPLICATION (8 rows) Time: 67ms total (execution 67ms / network 0ms) ``` Fixes: #92641 Epic: CRDB-18749 Release note: None
