WS-1966 Mark4 import workflow

There are 2 alembic scripts here:

1. Modifies the ingest_mk_four_obs workflow to rename mark4 directories when it's done to indicate the ingestion status.
2. Makes the mk_four_import workflow which simply runs the mark4_import script from /users/vlapipe/workflows/PROFILE/bin/mark4_import.

While looking at the ingest_mk_four workflow I realized that I forgot to set requires_lustre to true for the ingest_obs workflow. I set it manually on dev and test and it needed to be in the migration script so it'll be set on prod too.
