    Add rootwrap daemon mode support

    Add a configuration option 'use_rootwrap_daemon' to
    switch on the rootwrap daemon mode support. This
    option is switched off by default to keep the current
    behavior as is.

    The code honors the various options available in
    processutils.execute() like 'attempts', 'delay_on_retry'
    etc to ensure that we don't regress any current behavior.
