Problem statement

Add create-ucx-catalog to assign-metastore command so that UCX catalog is setup when attaching the metastore.

Note: The this PR did an attempt of adding the create-ucx-catalog to the assign-metastore, however, [some redsign](#2507) is required to run workspace level commands within the AccountContext`

Proposed Solution

See above

Additional Context

No response

Are we sure we want to do it at the same occasion. The challenge is that we recommend against setting a default storage location at the metastore, which means that we will have to provide a managed location at the catalog level. This will complicate an otherwise simple task.

No way to assign a workspace context to an account context. Creating documentation instead.
