Add submit argument to allow skipping virtualenv requirement install (#…

…421)

* Add submit argument to allow skipping virtualenv requirement install

* Revert "Add submit argument to allow skipping virtualenv requirement install"

This reverts commit 3dc873e.

* Switch venv options to be user-overwritable

Instead of using only `env_config`, we use the resolved options
which take into account options overwritten via CLI.
