When importing a module, Python first searches the current directory. See
https://docs.python.org/3/tutorial/modules.html#the-module-search-path. This
means that running something like `import certbot` from the root of the Certbot
repo will use the local Certbot files regardless of the version installed on
the system or virtual environment.
Normally this behavior is fine because the local files are what we want to
test, however, during our "oldest" tests, we test against older versions of our
packages to make sure we're keeping compatibility. To make sure our tests use
the correct versions, this commit has our tests cd to an empty temporary
directory before running tests.
We also had to change the package names given to pytest to be the names used in
Python to import the package rather than the name of the files locally to
accommodate this.

pip install generates a lot of lines of output that make it harder to see what
tox is running in general. This adds the -q flag to pip install.
At the same time, add `set -x` in install_and_test.sh and pip_install.sh so they
echo the commands they are running. This makes it a little clearer what's going
on in tests.
I didn't put `set -x` at the top or in the shebang, because moving it lower lets
us avoid echoing some of the messy if/then setup statements in these scripts,
which focussed attention on the pip install command.
