Data stores need to be set per machine.

[christinaholtNOAA]

Description

Currently the solution introduced for data ingest set the priority order and the list of data stores unilaterally in the run script scripts/exregional_get_extrn_mdl_files.sh. This should be done per-machine.

Solution

Add the default set of data stores to each of the ush/machine files and make it a configurable option. The WE2E tests that test pulling data from disk may want to set this option to disk only to ensure that the appropriate data source is being used for passing tests..
