Feature Propose

Allow to provide unified application launching environment from allzparkconfig.py.

Motivation

Allzpark can be launched in various way, e.g. from a Python virtual environment, or a Rez resolved context. And Allzpark can be backed with bleeding-rez or nerdvegas/rez, which has a bit different base environment control scheme between two approaches.

To overcome those differences and other surprises, allowing subprocess (application) parent environment to be set in allzparkconfig.py would be the most straight forward and effective solution.

Additional Features

• Add "Parent" tab in "Environment" dock page to show current parent environment.
• Add "Diagnose" tab in "Environment" dock page to show actual subprocess environment.
• Add "Code" tab in "Context" dock page to show script that is used to spawn shell from resolved context.
