VStorage: fixed permissions on shares config file

* Shares config file may contain cluster password,
  thus we need to set correct permissions on that.
* manage_package option is introduced.
* Don't ensure, that log directory exists. Log
  directory is created when vstorage-client rpm
  is installed.
