Fix prep-venv to install packages that are already installed in the host

It seems that pip --environment= is broken and ignores no-site-packages flag of
the virtual environment. This had a negative effect of not installing packages
that are available on the host, outside of the virtual environment. To work
around that we explicity activate the virtual environment and not pass
--environment to pip.

Change lava-tool auth-add to lava auth add

I've added a new command group 'auth' with the old auth-add command (renamed to
'add'). I also removed the old lava-tool console script as I intend to keep it
in the transitional package (lava-tool)

Remove the old lava_tool package.

This package only contains the legacy imports that pull in lava.tool code. I
plan on leaving this in lava-tool transitional package later on.
