Our current CLI tools and test runners have no standardisation on arguments. This makes it challenging for developers to quickly pick up new tools. The home argument is particularly confusing. Here is what a few tools/test currently provide:

wt tool

-? for help
-h for home

run.py

-h for help
-D --dir for home

test format

bad command for help
-h for home

cppsuite run

-h for help
-H for home

We should also document this in the wiki and coding guidelines.
