Do this by calling common_startup.sh prior to manage_db.sh in
run_test_wrapper.sh. Will require a rebuild of the testing-base image.
Also, have scripts in Galaxy root activate .venv if it exists.
Currently this is supported in the local runner (long running set_meta() can now be canceled the same as with jobs) and in the non-staging PBS runner.
There is a slight change to how new Metadata FileParameters are to be created in datatype.set_meta(), see the MAF datatype.
TODO:
Prevent editing of metadata on a running job when metadata is to be set externally.
Have datasets which were copied before job completion use the metadata from the original output dataset; currently .set_meta() is called locally on these.
