stream-clone: allow to change persistent-nodemap format during stream clone

Authored by marmoute on Jan 27 2022, 6:25 PM.



Persistent nodemap affect the store format. However it is fairly isolated and
fast to generate locally. So not making it a fixed part of the stream clone is

This allow clients without persistent-nodemap support (default for client
without Rust enabled, or simply older client). So it make it possible to enable
persistent nodemap on client, where it can provide a massive boost. without too
much consequence.

To do so, we stop using it in the advertisement requirements for streaming and
let the client add/remove the necessary file depending of its configuration.

We still send the files as it seems like a small save to not regenerate them.
In addition, the way we match them will overlap with the changelog-v2/revlog-v2
so we can't simply skip the associated patterns.

"fast to general locally" in the description needs a fix. I wonder if we should introduce a new set for such features, I expect similar cases to occur in the future.
