There seem to be some flakiness problems with these hooks. For non-SSL VCONNs they seem to be executed sometimes but not others: https://github.com/apache/trafficserver/pull/4576
When they do run for non-SSL VCONNs, TSVConnIsSsl() will erroneously return 1 for the VCONN. See https://github.com/apache/trafficserver/pull/4576
