ipsilon: increase memory on ipsilon vm's
    
    The ipsilon vm's have been swapping and using a lot of memory.
    We have memory to spare on those virthosts, so just bump it up to 32.
    Might be this will help some slowness / timeout issues some folks have
    seen authenticating to matrix and bugzilla.
