Is grpc keepalive supported ?

[bcoz123]

Thanks, Maxim,
I have another question,
If there are multiple grpc clients in the front,
Does nginx reuse the same connection to the backend grpc server?
By my test, it seems not.
In my opinion, http2 can support that.
And it can save resourses by avoid creating new tcp connection for each grpc
request,
Will you plan to support that in the future ?
Thanks
