tests: support CentOS Docker images.

- namespace & document test accounts in README.md
- standardize the password format everywhere, and ensure the passwords
  differ everywhere.
- Add MITOGEN_TEST_DISTRO environment variable.

1. Enable the virtual environment we just built ``source ../venv/bin/activate``
1. Install Mitogen in pip editable mode ``pip install -e .``
1. Run ``test``
# User Accounts
A set of standard user account names are used by in the Docker container and
also by Ansible's `osx_setup.yml`.
`root`
In the Docker image only, the password is "rootpassword".
`mitogen__has_sudo`
The login password is "has_sudo_password" and the account is capable of
sudoing to root, by supplying the account password to sudo.
`mitogen__has_sudo_pubkey`
The login password is "has_sudo_pubkey_password". Additionally
`tests/data/docker/mitogen__has_sudo_pubkey.key` SSH key may be used to log
in. It can sudo the same as `mitogen__has_sudo`.
`mitogen__has_sudo_nopw`
The login password is "has_sudo_nopw_password". It can sudo to root without
supplying a password.
`mitogen__user1` .. `mitogen__user21`
These accounts do not have passwords set. They exist to test the Ansible
interpreter recycling logic.
`mitogen__webapp`
A plain old account with no sudo access, used as the target for fakessh
tddests.
