Bugs: RANGER-1373
https://issues.apache.org/jira/browse/RANGER-1373

Repository: ranger

Description
-------

Test steps
1. Using following configuration to install the Ranger UserSync Process in install.properties.
unix_user=usersync
unix_group=usersync
2. Running updatepolicymgrpassword.sh or updatepolicymgrpassword.py to update policy mgr password.

The cause of the error is as follows:
The linux user processing logic of the installer for the Ranger UserSync Process, updatepolicymgrpassword.sh and updatepolicymgrpassword.py is inconsistent. The installer for the Ranger UserSync Process use configuration parameters to create linux user. However updatepolicymgrpassword.sh and updatepolicymgrpassword.py use hard code get linux user. In above test steps the usersync user and usersync group was created when installing the Ranger UserSync Process. ranger user and ranger group don't exist. In chown ${unix_user}:${unix_group} `dirname "${SYNC_LDAP_BIND_KEYSTOREPATH}"` the updatepolicymgrpassword.sh used ranger user and ranger group. The updatepolicymgrpassword.sh code is as following:
unix_user=ranger
unix_group=ranger
chown ${unix_user}:${unix_group} `dirname "${SYNC_LDAP_BIND_KEYSTOREPATH}"`.
The installer for the Ranger UserSync Process code is as following:
unix_user = globalDict['unix_user']
ownerName = mergeProps[unixUserProp]
groupName = mergeProps[unixGroupProp]
ownerId = createUser(ownerName, groupName)

We should also get linux user and group from configuration file in updatepolicymgrpassword.sh and updatepolicymgrpassword.py.
