pullbundle: attempt to save stablerange cache after each computation Since we do not serve the full repository, we use more stablerange starting from a random point. These are probably not loaded yet and should be cached. This is best effort caching, if we can't save them we won't.

pullbundle: add basic extension metadata

pullbundle: add a config option for the cache directory

pullbundle: add an output about the time spent slicing the set This will be useful to monitor overall performance.

pullbundle: add extension documentation

pullbundle: add an extra test showing how cache are reusable We issue a single final pull, most of its item are reusable.

pullbundle: add caching logic We now only generate a bundle once (and store it to disk). If we need it again, we use it directly from disk.

pullbundle: slice pull into multiple ranges We subdivide the set of missing revisions into multiple "range" using the "stable range" data structure. This slicing aims at maximizing the capability of the resulting ranges.

pullbundle: initial commit Right now, we do not do any slicing, but we install the wrapping and the tests.

test: update output to make streamv2 capabilities CORE-TEST-OUTPUT-UPDATE: 4bd6e444c76f
