Uses a bufconn listener between consul-template and vault-agent when
caching is enabled and either templates or a listener is defined. This
means no listeners need to be defined in vault-agent for just
templating. Always routes consul-template through the vault-agent
cache (instead of only when persistent cache is enabled).
Uses a local transportDialer interface in config.Cache{}.
