Daemon stops processing Kibana requests after restart about manticoresearch

[tomatolog]

I fixed the issue then daemon restarts and lost state he got from the Kibana at 152da28 - now it saves the state into manticore.json dashboard node then loads it too.

However if daemon crashed the state still be lost and we need to implement new binlog operations to save kibana state into binlog then restore it on binlog replay after daemon crash. But that should be done after refactor #879 finished.

I see that buddy handles most of the Kubana requests now and it might worth to remove that state management from the daemon and make buddy to handle these too. If we go this way there is no need to add new binlog operations. I could create the new branch there remove Kibana related state management from the daemon that allows these requests fall into buddy.

I confirm, it works fine now and restarting daemon does not cause any issues.

As for handling Kibana state management with Buddy - I think it's possible so we can discuss this idea.

That's done

@tomatolog can you list all what the daemon does now in terms of the Kibana support, so we can evaluate the list and decide whether it makes sense to move it all to Buddy?

here is a full list of endpoints daemon handles for compart mode

now it saves the state into manticore.json

@Nick-S-2018 pls inspect the state to figure out what endpoints from the list can modify it.
