Description

Implement a version of select_resources for Arvados.

You can get a dictionary of instance types with this:

api.config()["InstanceTypes"]

The select_resources method should, at minimum, accept a range of CPU core values (e.g. coresMin: 4, coresMax: 16) and then check the available InstanceTypes and assign the greatest core count available. For example, if the system is only configured with 2, 4, and 8 core nodes, it should assign 8 cores since it is in the range (4 - 16).

RAM and disk can also have a range. Just return the minimum value for now (this is the existing behavior).

Tell cwltool to use your select_resources method by setting the object field runtimeContext.select_resources.
