Missing documentation about OCPP configuration keys

[juherr]

Hi,

I was looking for the listing of all supported configuration keys and how to use them but didn't find it, except in the code:

OCPP keys are described into the specification.
I added OCPP keys that are not yet implemented (most of them are optional).

Maybe an explaination about the missing OCPP keys and a description about the CUSTOM keys should be added and updated in the documentation after each release?
