refactor(memory): make query rewrite provider-agnostic

Move query_rewrite from the honcho plugin to plugins/memory/ and
rename the auxiliary task key honcho_query_rewrite ->
memory_query_rewrite so any memory provider can use the same
rewrite path and model/timeout config block. No behavior change.
