    fix(deadlock): Cert rotation can deadlock on follower startup.

    On startup of a cluster, there is a chance that a follower can deadlock if it
    attempts to open a connection to another cluster member at the same time that
    the raft state machine is updating the shared root certificates.

    Fix the deadlock by making the stored list of per-cluster root certs an
    atomic value instead of guarding it with a mutex.
