Improve renaming of a Fabric warehouse

[FraLe]

When you rename a Fabric warehouse from [wh_a] to [wh_b], the underlying objects like tables, views, etc, still refer to [wh_a]. As a result references to these objects do not work anymore (code broken).  Please either

- disallow the renaming,

- or provide a 'copy warehouse A to warehouse B' feature

- or let the renaming take care of the renaming of the underlying objects in the warehouse
