commit 721887305038fe4449083eb6c33f355232c73555

    Set rootwrap daemon timeout for fullstack and functional tests
    
    Set a big timeout for rootwrap daemon in functional and fullstack
    tests. The value defined in 7800, the same as the Zuul jobs
    timeout.
    
    This timeout increase will prevent the daemon to close when
    executing a test root command, as described in the bug. An
    unexpected rootwrap daemon closure is not considered as a normal
    event during the test execution.
    
    The default value set in the configuration file is 600 seconds, the
    same as daemon default value. This timeout is increased only when
    OS_SUDO_TESTING=1, that means functional and fullstack tests, when
    using the script "tools/deploy_rootwrap.sh".
