Setting `oauth2_interceptRequest` if not already defined

[denisrossetre]

I have a common.http file that I import before every request. The script in this file sets the oauth2_interceptRequest to disable SSL verification:

    exports.oauth2_interceptRequest = function(request, context) {
      request.options = { https: { rejectUnauthorized: false }};
    };

Unfortunately, it seems that assigning to the oauth2_* variables invalides any access token obtained for the oauth2 prefix, and thus a new access token is retrieved for every request.

Note that I implement a OAuth2 Password Grant type returning an access token with a lifetime in hours, and there is no refresh token. Accordingly oauth2_keepAlive is not set.

Of course exports is empty when the common.http file is run, so I can't test that. Wrapping the above code in if (typeof oauth2_interceptRequest === undefined) does not seem to work.

What can I do?
