Will there be a plan to break down patch and contribute some patches to the upstream?

Why you need it?

When I read the source, I found that Higress uses a single patch to record the change from the upstream projects.
Therefore, Higress now have some huge patch file (9000 lines+), which will make the maintenance very hard.

Some features require patching several projects. For example, to add sentinel support, both go-control-plane and istio are patched. If we can move the patch into upstream, we can avoid some patches.

How it could be?

Break down the patch into multiple ones according to their features.
If possible, we can contribute some patches back to the upstream.

Great idea, we'll be doing this during upgrade work #8, and we'll do our best to get most of these changes accepted by the upstream's community.

@spacewander I am +1 on this. We should reduce patches, otherwise it will be hard to maintain.
