Dynamically source variables from install.conf each time the app is opened

[bantucaravan]

Variables from install.conf are currently manually hardcoded into the wrap files upon installation (for example here:

jupyter-app/install

Line 223 in 2549f59

sedvar "${ABS_MID_WRAP}" VIRTUAL_ENV JUPYTER_BIN JUPYTER_CMD JUPYTER_NOTEBOOK_DIR ABS_INNER_WRAP BROWSER_CMD

).

To allow changing virtual envs (for example), I would like to source the variables in the wrap scripts each time app is opened.
Is there any reason why this is not done currently?
