* Remove signature checks from unittests. Would need to export
signature from client/fetcher (unwanted). Can't figure out a better way.
e2e test completes in ~4sec and runs automatically.
So seems like a acceptable tradeoff.
* list object is now signed, but not verified. If we start to verify the list
we will have to adapt the e2e test to restore the previous list.
Otherwise there could be conflicts between dev and release keys.
* fetch latest version when older than 2 weeks
* extend hack upload tool to pass an upload date
* Revert "config: disable user-facing version Azure SEV SNP fetch for v2.8 (#1882)"
This reverts commit c7b22d314a.
* fix tests
* use NewAzureSEVSNPVersionList for type guarantees
* Revert "use NewAzureSEVSNPVersionList for type guarantees"
This reverts commit 942566453f4b4a2b6dc16f8689248abf1dc47db4.
* assure list is sorted
* improve root.go style
