[PR] Introduce ProxyingMetadataHandlerProvider to decouple JaninoRelMetadataProvider from SQL Federation [shardingsphere]

["linghengqian (via GitHub)" <gi...@apache.org>]

linghengqian opened a new pull request, #34980:
URL: https://github.com/apache/shardingsphere/pull/34980

   Fixes #33139 .
   
   Changes proposed in this pull request:
     - Introduce ProxyingMetadataHandlerProvider to decouple JaninoRelMetadataProvider from SQL Federation.
     - Also for #29052 . I would say that the workaround for https://github.com/apache/calcite/pull/2653 is still not enough to completely avoid janino. The current PR is used to test E2E CI.
     - Support connecting to OpenGauss via DistSQL in Proxy Native.
