[robot] Add libraries and resources used by the suite

Add a series of libraries and resources that are used by the suite setup
and test cases functionality.

-  Libraries - Libraries written in python mostly to serve the
        installation and deployment of StarlingX from robot test cases.
-  Resources – Libraries in robot format that are used as a
         pool of keywords to be used by the entire set of test
         cases.
-  Utils – Libraries written in python that expose
         functionality to configure the framework at host
         machine level.
-  Variables – Global variables that are
          used to setup the framework as well as
          test cases.
