Adjust resource requirements for processes to sensible defaults

[drpatelh]

The label for each process may or may not have been guestimated for each process. Would be good to test the pipeline on a largeish dataset so we can set sensible defaults. For example, I have uploaded the NF reports here after running -profile test_full.

execution_trace.txt
execution_timeline.html.txt
execution_report.html.txt

PS: Sorry added a .txt extension to the html files because GitHub doesnt like them.

I suspect this will happen organically as the pipeline is tested more frequently on datasets of varying size and on different compute environments so will close for now. The current defaults seem to be doing the trick.
