Data importer, min priority and min pogram priority

[Kirk-V]

The scheduler expects to receive data with a lower priority than the cli argument passed to the data_importer. This gets a bit fuzzy with the wording as we now should want to get rows from the data with priorities that are lower...AKA max priority instead of min priority.

Also, we should consider bringing any default values that are set from arguments outside of the data importer module. We will discuss this though.
