    Fix to show version information from root API.

    When the user hits http://serv_api:8118 instead of version information
    kingbird returns 401 authentication.Introduced a new section
    pecan configurations and pecan hooks to fix this error.
    Added test-cases, made trivial changes for tempest tests and refactored
    some code.
