Skipping z-stream test
Skipping two api tests based on open BZs
- Skipping test_cv_promote_badenvironment_negative using bug 1091494. This bug is written for CLI but is reused here for API. A new bug will be created in future if need be.
- Skipping test_post_and_get using 1151240.  Earlier this was skipped using 1122267.  But 1122267 is closed in favor of 1151240
