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.

== New Features == * `hg mv -A` can now be used with `--at-rev`. It behaves just like `hg cp -A --at-rev`, i.e. it marks the destination as a copy of the source whether or not the source still exists (but the source must exist in the parent revision). * New revset predicate `diffcontains(pattern)` for filtering revisions in the same way as `hg grep --diff pattern`. * The memory footprint per changeset and per file during pull/unbundle operations has been significantly reduced. == New Experimental Features == == Bug Fixes == == Backwards Compatibility Changes == == Internal API Changes == * `merge.update()` is now private (renamed to `_update()`). Hopefully the higher-level functions available in the same module cover your use cases. * `phases.registernew` now takes a set of revisions instead of a list of nodes. `phases.advanceboundary` takes an optional set of revisions in addition to the list of nodes. The corresponeding members of the `phasecache` class follow this change. * The `addgroup` member of `revlog` classes no longer keeps a list of all found nodes. It now returns True iff a node was found in the group. An optional callback for duplicated nodes can be used by callers to keep track of all nodes themselve. * The `_chaininfocache` of `revlog` classes has been changed from a dict to a LRU cache.
