Dean Troyer 5686dbc45d Add global venv enable/disable knob
Adds USE_VENV to globally enable/disable use of virtual environments.

ADDITIONAL_VENV_PACKAGES is used to manually add packages that do not
appear in requirements.txt or test-requirements.txt to be installed
into each venv.  Database Python bindings are handled this way when
a dataabse service is enabled.

# as well as all of the lib/* files for the services have been sourced.

# For clarity, all functions declared here that came from ``stack.sh``
# shall be named with the prefix ``stack_``.
