fatcat_tools should not import from fatcat_web

[bnewbold]

In the current code architecture, importing from fatcat_web executes fatcat_web/__init__.py, which does a whole bunch of stuff, and prints status to stderr. This is kind of confusing! It would be better if fatcat_tools never imported from fatcat_web, and only did imports in the other direction.

Could work around this by moving or copying the relevant code (currently, just some search queries for container status) to fatcat_tools.

Fixed!
