Hi everyone,

I would like to start a discuss on FLIP-295: Support persistence of
Catalog configuration and asynchronous registration

Currently, when using Catalog in Flink, it is necessary to re-register
each time. Therefore, providing persistent configuration for Catalog
will make its management more convenient.
Especially for SQL management modules such as Flink SQL gateway and
SQL client, it eliminates the hassle of registering every time before
starting.

Look forward to your opinions!
