Release 0.10

Details

• This release will include a major overhaul of Hegel internals to create a clear and unambiguous delineation between frontends and backends.
• Integration of the Tink backend will be dropped as we have very little documentation and nearly no functional examples of it working in its entirety.
• The /versionz endpoint (previously /_packet/version will be dropped as the same information is available in /healthz.
• Removal of the spot endpoints in the EC2 frontend.
• Kubernetes options changed to be prefixed with backend name.

Everything for the release seems to be in-place. I still need to validate the Kubernetes backend works after receiving a few tweaks.
