I would like to change the following const values ([env.rs](http://env.rs/) file in linkerd2-proxy\linkerd\app\src\ repository):  
`/// Configure the stream or connection level flow control setting for HTTP2.`  
`///`  
`/// If unspecified, the default value of 65,535 is used.`  
`const ENV_INITIAL_STREAM_WINDOW_SIZE: &str = "LINKERD2_PROXY_HTTP2_INITIAL_STREAM_WINDOW_SIZE";`  
`const ENV_INITIAL_CONNECTION_WINDOW_SIZE: &str =`  
` "LINKERD2_PROXY_HTTP2_INITIAL_CONNECTION_WINDOW_SIZE";` However, if I change them will they be respect?  
Also, to apply them would a config map be the way to go or is there any better solution? (edited)

Context:  
I am trying to improve network payload flow in the same manner as we could for Linkerd1 by changing in the h2 protocol the value of the variable: `initialStreamWindowBytes` (edited)
