Update googletest to latest master

Local changes required:
-Added googletest tests to CI script.
-For merge conflicts, preferred upstream in all cases.
-Added in a -Wno-unused-parameters, and removed some "-pthread"'s to
 clean up obnoxious compiler warnings about unused flags.
-Added rules_python to WORKSPACE to make googletest happy.
-Update *_CASE_P to *_SUITE_P
