stream-clone: allow to change persistent-nodemap format during stream clone 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. Differential Revision: https://phab.mercurial-scm.org/D12096
