Release v0.8

[LysandreJik]

Starting in April we started implementing a monthly release schedule: v0.5.0 in early April, v0.6.0 in early May. v0.7.0 was released shortly after as a commit was lacking from v0.6.0 and was needed for the evaluate release.

I am proposing to release v0.8.0 next week, which would act as the successor to v0.6.0. The v0.8.0 milestone contains three PRs which need to be merged:

• Remove history from Keras model card #869
• Refine 404 errors #878
• metadata_update: work on a copy of the upstream file, to not mess up the cache #891

Additionally, there are a few deprecation warnings that should now error out. This includes the login command as describe in #827, cc @Pierrci

If you think the monthly pace is suiting this library ATM, I'm fine with it. Otherwise I'd be fine slowing down the release cycle as well.

I think the monthly pace suits this library quite well: we want big features like the ability to open PRs/discussions rather rapidly; as it won't make it in this release, I think it would be a bit painful to wait two months after v0.8.0 in order to have that feature in a release. Having a monthly pace solves that problem with no downsides :)

Two PRs ought to be in this release as well:

• Remove deprecations #910, which removes all deprecation around v0.8.0
• Add request ID to all requests #909, which adds the X-Request-ID error code to error messages, so that the backend team may be more helpful in debugging user issues.

I think we can close this :)
