[keycloak-dev] LDAP No Import in Master

[Bill Burke]

LDAP No Import in master.  I ended up creating a UserModel in-memory 
pojo, and passing it to the import command and that worked for most of 
situations.  There were some other minor fixes to get it to work.  The 
only issue I have now is that if there is no mapping for an update, no 
exception is thrown and the changes are just lost with no warning.  
Runtime should throw an error in this situation.  Not sure the best way 
to handle it for the moment, so I'm going to let it stew in my brain for 
a little while.

Also added "remoteImportedUsers" and "unlinkUsers" operations. This will 
allow people to migrate from import mode to no import mode.

Cheers,

Bill
