[keycloak-user] WARNING: breaking User API backward compatibility

[Bill Burke]

FYI:

Starting in 2.3, there will be a number of user SPIs and APIs that will 
be refactored or deprecated.  UserModel, UserFederationProvider, 
UserCredentialModel, PasswordHashProvider, and UserFederationManager are 
being refactored. UserFederationProvider is also being @Deprecated.  
Code will break, and you'll have to figure out how to start using the 
new UserStorageProvider SPI, or update UserFederationProvider 
implementation.  You'll start seeing changes pop up in master over the 
next few weeks.

Regards,

Bill
