    Allow configurable ProcessLauncher liveness check

    The current interval between ProcessLauncher checks of whether
    a child process has exited - 0.01s - prioritizes fast respawning of
    children at the expense of cpu usage. This tradeoff may not be
    appropriate for all clients of the class, so this patch makes the
    interval configurable. The current interval remains the default
    to avoid changing expected behavior.

    This patch was motivated by unnecessary idle cpu usage of the
    Neutron service when configured to use ProcessLauncher-managed
    worker processes.
