I think you've got to update for 3.13,

change to

for ep in entry_points().select(group="..."):

vs.

for ep in entry_points().get("...", [])

in pfb.py and users.py

I'd like to refactor some of the stuff here - the profile listing support it's polluting the top level commands.

Let's see if we can just move those under configure. e.g.

instead of top level commands, let's do this:

gen3 configure list-profiles
gen3 configure show-profile --profile MIDRC_prod

and then the existing:

gen3 configure --profile new_profile ...
