Is it possible to override or set request\_id in logging?  
We are using MDC, Mapped Diagnostic Context, to set a transaction/context id, such as every request logs a transaction log.  
But the few times there is a log message from elasticsearch, this is done in another thread and there is no transaction id.  
Or if it's possible to use an supplier that sets the transaction id in a thread?

Checked the code, found out that the requestid is set in the transport interface. But didnt find a good way of how to oveeride it.

[elasticsearch[_client_][generic][T#4]] INFO o.e.c.t.TransportClientNodesService failed to get node info for {#transport#-2}{q6...}{...}{...}, disconnecting...
