vendor requests_kerberos v0.12.0 (#268)

Pending upstream changes will cause significant breakage; just embed a working one.

* updated setup.py kerberos extras_require to directly install pykerberos/winkerberos as necessary (and drop requests_kerberos)
* updated .coverargerc to exclude vendor subpackage

+requests Kerberos/GSSAPI authentication library
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Requests is an HTTP library, written in Python, for human beings. This library
+adds optional Kerberos/GSSAPI authentication support and supports mutual
+authentication. Basic GET usage:
+
+    >>> import requests
+    >>> from requests_kerberos import HTTPKerberosAuth
+    >>> r = requests.get("http://example.org", auth=HTTPKerberosAuth())
+
+The entire `requests.api` should be supported.
