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.

'''http authentication with factotum This extension allows the factotum(4) facility on Plan 9 from Bell Labs platforms to provide authentication information for HTTP access. Configuration entries specified in the auth section as well as authentication information provided in the repository URL are fully supported. If no prefix is specified, a value of "*" will be assumed. By default, keys are specified as:: proto=pass service=hg prefix=<prefix> user=<username> !password=<password> If the factotum extension is unable to read the required key, one will be requested interactively. A configuration section is available to customize runtime behavior. By default, these entries are:: [factotum] executable = /bin/auth/factotum mountpoint = /mnt/factotum service = hg The executable entry defines the full path to the factotum binary. The mountpoint entry defines the path to the factotum file service. Lastly, the service entry controls the service name used when reading keys.
