>   Discussed with Natty about LdapGroupMapping, we need to improve it so that: 
> 1. It's possible to do different group mapping for different users/principals. For example,
AD user should go to LdapGroupMapping service for group, but service principals such as hdfs,
mapred can still use the default one ShellBasedUnixGroupsMapping; 
> 2. Multiple ADs can be supported to do LdapGroupMapping; 
> 3. It's possible to configure what kind of users/principals (regarding domain/realm is
an option) should use which group mapping service/mechanism.
> 4. It's possible to configure and combine multiple existing mapping providers without
writing codes implementing new one.
