[DISCUSS] Per-user Iceberg warehouse with bring-your-own S3 storage

Hi all,

I've opened issue #5135 proposing a per-user Iceberg warehouse model for
Texera, where each user registers one or more warehouses backed by their
own S3 bucket (Bring-Your-Own-S3). This builds on the REST Catalog Service
work from #4126 and makes Lakekeeper multi-tenant, so storage cost follows
the data owner.

The issue lays out two alternative designs (Warehouse↔CU binding vs.
Warehouse↔Execution binding), the registration / runtime flows with
sequence diagrams.

For details, please check the link below. I'd really appreciate your
feedback.

Thanks!
