Allow option to suppress info messages that are sent to stderr

As per https://github.com/pypa/pipenv/issues/628 and https://github.com/pypa/pipenv/pull/630, some output, e.g. courtesy notices and messages like

Loading .env environment variables…

are sent to stderr instead of stdout. This is somewhat unexpected behaviour as these are clearly not error messages. In fact, these messages are polluting some of our error logs. It would be really useful to have an option to completely suppress these messages, e.g. by allowing the --bare flag for the run and shell commands.

i don’t want to redirect all of my stderr though, just this one message; one can do what @sudeshjethoe suggested and pipe stderr into grep -v then pipe the stdout of that back to stderr, all the while redirecting stdout to null, but it seems like a really convoluted (and limiting) solution for removing a non-critical message from stderr

for anyone else looking to do this, here’s my current solution:

# pipenv run python script.py 2> >(grep -v "Loading .env environment variables" 1>&2)
