> Found while tracking TS-4507 and original fix combined with that fix.
> In ProxyClientSession::state_api_callout we schedule_in 10ms in the future if
> the plugin lock is not acquired. Saw ASAN use-after-free crashes when the
> Http2ClientSession is deleted but the schedule event remains and is
> triggered. Added a schedule_event member to track this case and cancel any
> outstanding schedule events on free.
