API for GET requests with automatic error handling

The keyword "Get Data From URI" issues a GET request for the
specified URI through the specified session, FAILs if the
request returns an error (with logging that error into Robot
logs and returns the data on success. Success is currently
defined as "returned status code 200" and the method is
hardwired to GET so this keyword is not useful for making
non-data-getting requests like POST or for GET requests
that don't return any data and return an OK-like status code
(2XX where XX != 00).
