Review request for ranger, Don Bosco Durai, Madhan Neethiraj, Ramesh Mani, Selvamohan Neethiraj,
and Velmurugan Periasamy.


Bugs: RANGER-208
    https://issues.apache.org/jira/browse/RANGER-208


Repository: ranger


Description
-------

Currently both the Unix user authentication and Unix user/group sync happens from the same
process. Since both the tasks are independent of each other, they should be run as separate
process.
This way if the user/group sync process is down the authentication wont be affected and vice
versa.

Testing
-------

Implementation :
   1] Separated the user sync and user auth codebase [ with changes in assembly ]
   2] Modified installation scripts
   3] Added a package in usersync named service
   4] Added scripts to start sync/auth processes : user-sync-start.sh and user-auth-start.sh

Tested :
   1] Tested unix user sync
   2] Test Ldap user sync ( pending )
   3] Test AD user sync ( pending )
   4] Tested DB user Authentication
   5] Tested Unix user Authentication
   6] Test Ldap user Authentication (pending)
   7] Test AD user Authentication (pending)
   8] Tested with Admin & (user sync & user auth) on same machine
   9] Tested with Admin & (user sync & user auth) on diff machine
   10] Tested User Sync being run as non-root user
   11] Tested User Auth being run as non-root user ( Fails! Because access to /etc/shadow
is allowed only to root user . For this added a check in start script so only root user can
run User Auth process)
