Add a ProxyStorage that route request to temporaryStorage or longTermStorage automatically.
@ametaireau review.
Factorise the creation of ProxyMethods (methods that should be called on bothStorage.)
Handle object data for certificateData.
Rename volatileS et persistantS _volatileStorage and _persistentStorage.
Store the creation date and the last update date on the persitent storage.
The MSISDN validation set persistentStorage and prune volatileValidationData.
@tarekziade review.
persistant to persistent in config files.
Don't provide direct access to volatile and persistent storage from the proxy.
StorageProxy should be just a backend and we should be able to use redis directly.
