pkg/cri/streaming: increase ReadHeaderTimeout

fuweid · fuweid · commit 460b0533b2c0 · 2022-08-18T07:42:12.000+08:00
It is follow-up of #7254. This commit will increase ReadHeaderTimeout from 3s to 30m, which prevent from unexpected timeout when the node is running with high-load. 30 Minutes is longer enough to get close to before what #7254 changes. And ideally, we should allow user to configure the streaming server if the users want this feature. Signed-off-by: Wei Fu <fuweid89@gmail.com>
