test_uri_length_limit follows proxy and hits wrong localhost

[Angus Lees]

test_uri_length_limit honours HTTP_PROXY (if set). This means the test queries to http://localhost:$port/ hit the wrong localhost when $HTTP_PROXY is another host, resulting in a meaningless test scenario, and apparent failures with HTTP status codes other than REQUEST_URI_TOO_LARGE (414).

I've got a quick fix for this.

Oh, nevermind. Looks lik your fix https://review.openstack.org/#/c/99823/ didn't get linked in to the bug.

    Don't follow HTTP_PROXY when talking to localhost test server

    Unlike urllib2, requests honours HTTP_PROXY by default. This meant
    test_uri_length_limit's test queries to http://localhost:$port/ would
    hit the wrong localhost when $HTTP_PROXY was another host - resulting in a
    meaningless test scenario and apparent failures with HTTP status codes
    other than the expected REQUEST_URI_TOO_LARGE (414).

    This change forces requests to go direct for those test queries.
