Allow Disabling Pipenv Check #1612

When I start VSCode with the vscode-python extension I get the warning:

Workspace contains pipfile but attempt to run 'pipenv --venv' failed

I don't need pipenv support and my venv is inaccessible within a virtual machine anyway. It would be nice if there were a setting to prevent vscode-python from trying to run pipenv even if there is a Pipfile in the workspace.
