Start rindex tests
    
    Add couple of tests for the new lookup command using the daemon.
    
    To make the tests faster, we use 1 second io timeout. This is much
    faster then real usage, but still takes about 3 seconds per test when we
    add a lockspace. Need to check how to make this faster.
    
    Unfinished: cover all commands.
