Auto merge of #2578 - micbou:urllib-compatibility, r=Valloric

[READY] Import urljoin and urlparse from ycmd.utils

See https://github.com/Valloric/ycmd/pull/724. This also fixes a regression in startup time on Python 3 because importing `futures.moves` was calling [the `import_top_level_modules` function](https://github.com/PythonCharmers/python-future/blob/master/src/future/moves/__init__.py#L7-L8) which is slow.

Fixes https://github.com/Valloric/YouCompleteMe/issues/2577.
