[Developers] Removing deprecated influence type keys

[Bryan Cheung]

The two influence types, Influence Node and Peer Relationship, have  
deprecated keys into the creator's (mikelove) personal domain.  A good  
amount of time has passed since the influence types were promoted to  
freebase commons, and I'd like to remove the key aliases to the old  
domains.  This is a last call for anyone still using the influence  
type keys in the namespaces /user/mikelove/default_domain or /user/ 
mikelove/influence .
