### Is your feature request related to a problem? Please describe.

Polaris provides generic tables apis which provide a solution for delta table, but there is an official spec for delta table now, should we support this spec as well?

Start by reading the linked Delta REST Catalog specification and reviewing how Polaris currently exposes generic table APIs. Determine the required Delta-specific scope and integration points before proposing an implementation; done means the official Delta REST Catalog APIs are supported with corresponding validation and coverage.
