swh.indexer.storage: Unify get_indexer_storage function with others

Trying to sense a bit better on how to converge with what's described in the hackmd discussion [1]

(also, we have those kinds of tests on at least the storage and search).

Impacts [2]:

• D4272: swh-indexer

• swh-web!1020 (closed): swh-web
