> [~daryn] reported that adding a new resource to a conf forces a complete
> reload of the conf instead of just loading the new resource. Instantiating a
> {{SSLFactory}} adds a new resource for the ssl client/server file. Formerly
> only the KMS client used the SSLFactory but now TLS/RPC uses it too.
> The reload is so costly that RM token cancellation falls behind by hours or
> days. The accumulation of uncancelled tokens in the KMS rose from a few
> thousand to hundreds of thousands which risks ZK scalability issues causing a
> KMS outage.
