test: Rest catalog integration test.

We need to do integration test for rest catalog against rest catalog server. Tabular has an docker image for this.

I'm happy to take this, I have implemented similar things in icelake.

@liurenjie1024 Thanks for raising this. This made the testing on PyIceberg much easier. Also, I've created a similar PR for duckdb: duckdb/duckdb-iceberg#27 which might provide some inspiration.

Thanks! I will take a look when implementing this.
