    stream-clone: allow to change persistent-nodemap format during stream clone · de3ac3d2c60b
    Pierre-Yves David authored
    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
    useful.
    
    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.
