[24.0] Use hg clone --stream to clone repos

[mvdbeek]

We're exceeding (already generous) timeouts in test_0110_reset_metadata_on_all_repositories

The docs says this about --stream:

In normal clone mode, the remote normalizes repository data into a common exchange format and the receiving end translates this data into its local storage format. --stream activates a different clone mode that essentially copies repository files from the remote with minimal data processing. This significantly reduces the CPU cost of a clone both remotely and locally. However, it often increases the transferred data size by 30-40%. This can result in substantially faster clones where I/O throughput is plentiful, especially for larger repositories. A side-effect of --stream clones is that storage settings and requirements on the remote are applied locally: a modern client may inherit legacy or inefficient storage used by the remote or a legacy Mercurial client may not be able to clone from a modern Mercurial remote.

I think this is overall beneficial for us, since we often need to clone few but large files (think compressed or binary test data).

I have no idea if that solves the test timeouts, it's marginally faster locally, but this also doesn't time out locally.

With the changes test_0110_reset_metadata_on_all_repositories takes 89 seconds, without it's 134 seconds ... caveat is I only ran it once, but it also seems like the tests are now passing when they consistently failed before.

Hmm, still timing out :(

[mvdbeek]

ok, 1 out of 3 times out ... I'll put an xfail on it, no need to hold up unrelated PRs

Thanks!
