requests==2.11.0 is now checking header parameters for string or buffer types. We were passing SUPPORTED_ONEVIEW_VERSION as int, but now it's not allowed. This patch str's SUPPORTED_ONEVIEW_VERSION before passing it to requests. This patch also fixes a transient error occuring due to simultaneous access to constants in 'fixtures.py'.
