    Switching how we handle sessions in p11_crypto

    Previously, we were trying to use pre-existing sessions and
    semaphores to deal with our concurrency issues. However, this
    led to HSM memory exhaustion due to the sessions never closing.
    To mitigate this, I'm switching to a model where we're opening
    and closing sessions as we need them. By extension, this removes
    our need for semaphores. We can explore ways of making this more
    efficient in the future, but this change should address the
    outstanding issue.
