Add unique parameter i.e. joey_remote_url or joey_arg_url for remote m2m data exchange

[tpmccallum]

If a caller is using the multipart endpoint to run a function, Joey should allow the caller to specify a joey_remote_data_url as one of the parameters i.e. if the caller is executing a function that edits a large video/image they should not be required to have that image on their local device (in order to add the data as a function argument/parameter).

This way callers can be light clients like mobile phones, yet still initiate high performance/compute intensive/data intensive processes from a small remote device.

How would this work?
If call to /api/multipart/run contains a string called joey_remote_data_url then Joey need to go and fetch the raw data at that URL's location and pass it into the ssvm function call (all server side)

This is now achieved with the fetch_ prefix

This works for both POST and GET requests
