adamverse: add --no-deps to pip install commands

In various roles I maintain I use `python3 -m pip install` to
directly install a Python project (usually a fedora-messaging
consumer), to avoid the pointless bureaucracy of packaging them.
The roles install all the deps of these projects as packages
first, so pip doesn't have to install any deps, it only installs
the project itself. Well...that's the idea. It's possible for
this to go wrong (say I forget to update the roles when adding
a dep to the project), and in that case I think we'd rather have
things blow up (so I know something's wrong) than have pip
silently install some random upstream wheel system-wide to make
it work. The intent is that all the deps still come from proper
Fedora packages, only these projects themselves get installed
directly.
