Description

I submit PR https://github.com/apache/dolphinscheduler-website/pull/555 to ds website about how to use python virtualenv to run python script in virtualenv. But maybe we should support a better way to run python script with virtualenv instead of create multiply environment.

Cause environment is for all task attribute, but virtualenv only for python interpreter. for now is more look like

|-- parent python interpreter
|-- parent python interpreter virtunlenv1
|-- parent python interpreter virtunlenv2

All python virtualenv is visible to all type task. But I think a better way is virtualenv only for python task

|-- parent python interpreter
    |-- parent python interpreter virtunlenv1
    |-- parent python interpreter virtunlenv2

which mean we would have less python environment name, and each python environment have multiply virtualenv selection.

Code of Conduct

Contributor guide

Research direction
Investigate how virtualenv can be scoped to Python tasks rather than globally in the DolphinScheduler task environment. Examine the current environment structure and propose a design for per task virtualenv management without affecting other task types.
