What changes were proposed in this pull request?

This is a basic implementation of the Iceberg REST Catalog as a service embedded within HMS.

Why are the changes needed?

For Hive users that have started using Iceberg to store data and want to expose those same tables to external query engines, implementing the Iceberg REST catalog embedded within HMS allows an easy upgrade and deployment path.
Although a dedicated service to host the REST catalog is certainly desirable, it also implies deploying and managing another service.

Does this PR introduce any user-facing change?

It does since HMS then 'hosts' a servlet that implements the Iceberg REST Catalog API.

Is the change a dependency upgrade?

No.

How was this patch tested?

Unit tests.

(Restart of #5145 )
