Add function for get_image_bundle_by_container_id and tests

[mharista]

Similar to what is in Ansible module_utils.

Current implementation is the same across all API versions.

def get_image_bundle_by_container_id(self, c_id, start=0, end=0, scope='false'):
        ''' Returns a list of ImageBundles applied to the given container.
            Args:
                c_id (str): The container ID (key) to query.
                start (int): Start index for the pagination. Default is 0.
                end (int): End index for the pagination. If end index is 0
                    then all the records will be returned. Default is 0.
                scope (string) the session scope
        '''
        return self.clnt.get('/provisioning/getImageBundleByContainerId.do?'
                             'containerId=%s&startIndex=%d&endIndex=%d&sessionScope=%s'
                             % (c_id, start, end, scope),
                             timeout=self.request_timeout)
