    Move conductor wait_until_ready() delay before manager init

    The Service base class already waits for conductor to be responsive
    before allowing service startup to continue. However, it does this
    after the manager __init__, which could do some things expecting
    conductor to be up (and does now in compute). This moves the check
    and wait loop above the manager init so we don't start anything in
    the manager until we know conductor is alive.
