Sergey Nuyanzin updated FLINK-25788:
------------------------------------
    Description: 
Currently the only work around to see available connectors is to create a table 
for non-existing connector and run sql over that table. In Exception there will 
be a list of available connectors.
The idea is to have command like
{code:sql}
Flink SQL> SHOW CONNECTORS;
+----------------+--------+
| connector name | type   |
+----------------+--------+
|     opensearch |  sink  |
|        datagen | source |
|      blackhole |  sink  |
|          print |  sink  |
+----------------+--------+
5 rows in set

{code}
