SERVER-97431 introduced a smoke test suite to cover each user command under the Catalog and Routing umbrella.

Due to unaddressed dependencies (SERVER-98315), a few relevant commands are still missing from the list.

The objective of this ticket is to ensure that setUserWriteBlockMode gets also included into the smoke test suite: to achieve this, relevant test cases can be extracted from jstests/sharding/set_user_write_block_mode.js and migrated into a new test file under {jstests/noPassthrough/catalog.
