HTTP2 is supported by OkHttp and it's enabled by default. There's also support in Apache HC5. We should add the support for this within this issue.

hello @OlgaMaciaszek , feign.hc5.ApacheHttp5Client does not support the http2, but feign.hc5.AsyncApacheHttp5Client supports http2

I've sorted out the clients that support the http2 protocol. AsyncClients is the best for supporting the http2 protocol.

client	http/2.0
feign.Client.Default	no
feign.hc5.ApacheHttp5Client	no
feign.okhttp.OkHttpClient	yes
feign.http2client.Http2Client	yes

AsyncClient	http/2.0
feign.AsyncClient.Default	yes
feign.hc5.AsyncApacheHttp5Client	yes
ffeign.okhttp.OkHttpClient	yes
feign.http2client.Http2Client	yes

Maybe we need to implement the http2 protocol on the basis of Async feign flow #511.
