feat(core): Add support for Container and TTL nodes

[ceache]

Also add support through transations.

Closes #334, #496

[ceache]

Still missing tests. Will need to update the harness to configure Zookeeper to enable extended types.

@ceache just curious on the status here? I assume you've just been busy? Or have you abandoned this for some reason and forgot to close it?

[ceache]

Well, I have been incredibly busy, sorry about that. But not idle. I have implemented a Wireshark zookeeper protocol dissector (I'll link it here) and confirmed the issue is indeed in zookeeper. https://issues.apache.org/jira/browse/ZOOKEEPER-4026 The PR is otherwise not wrong, albeit it needs a little tidy up before merge. But I am not sure how to go about testing it. (be permissive?)

Haha, I also have been working on a Wireshark zookeeper dissector the last few months in my spare time as a way to learn C/wiresharp APIs/understand the ZK protocol at a deeper level: https://gitlab.com/wireshark/wireshark/-/merge_requests/528

I've had to put it on hold the last few weeks as we somewhat spontaneously decided to buy a house so I've been busy with that, but hope to pick it back up during my time off over the holidays.

I would say for testing, being permissive is fine with me. I'm also completely fine with letting this sit for a bit longer to get a ZK release with the bugfix if that makes testing this simpler... whatever you prefer/think is wisest. It would be nice to have a test, but I defer to your judgement. I just wanted a status update since there'd been no update since June.

Mine is a LUA dissector https://github.com/ceache/zab_dissector

Hi!

In short I've found myself in the need for nodes with TTL. I'm not entirely sure how this PR is blocked, but I figured it might be good enough for me. I've forked, merged it in and added a simple test to check if persistent TTL nodes behave as expected. They work great as far as I can tell. You can find it here: https://github.com/Traktormaster/kazoo/tree/ttlme

I'm not sure how to offer that commit into this PR myself, but you may find it useful when getting back to work on this.

Thanks!
