This PR replace #1176
A different approach is used here
Mainly we try to read 1 byte from the stream in a sync way, since we didn't send anything yet we should receive a WouldBlock io error, if we doesn't receive this it either means :
Retrying here should be safer since we don't consume request, i still use a middleware so user will opt in for this feature
I only handled the h1 connection closed error here, we could add other cases later when request could be retried safely in those cases
