'Read information and transform it
The values that are returned by BIG-IP in the f5-sdk can have encoding
attached to them as well as be completely missing in some cases.
Therefore, this method will transform the data from the BIG-IP into a
format that is more easily consumable by the rest of the class and the
parameters that are supported by the module.'
