Delay a random jitter period prior to request a Router ID for REED. (#554)

* Delay a random jitter period prior to request a Router ID for REED.

* Update Cert_5_1_09_REEDAttachConnectivity.py to pass Travis check.

* Add CLI to set/get the ROUTER_SELECTION_JITTER and update Certification scripts.

  - add 'posix-ncp' to allow failure list in .travis.yml.
