[release] v0.8.0

[Andy Goldstein]

Hi all, we're thrilled to announce the release of kcp v0.8.0! This is another huge milestone, with lots of new features and bug fixes. Highlights include:

• The syncer is more secure, requiring an exact match on SyncTarget UID
• APIExports can use permission claims to request access to built-in APIs (e.g. ConfigMaps) and APIs provided by other APIExports
• The kcp authorizers now add extensive audit annotations during the authorization process, significantly improving the detail in the audit log for the reasoning behind each authorization decision
• We've started transitioning the kcp code base to structured, contextual logging
• kcp and the syncer now support syncing autoscaling APIs
• We've begun building out the cache server infrastructure, continuing our preparation for multiple shards
• We squashed a major bug that kept workspaces from being deleted and which was also a performance issue
• You can now no longer edit immutable metadata fields (such as creation timestamp) for Kubernetes types installed as CRDs (such as Deployments)
• Resources and namespaces are properly cleaned up when being deleted
• You no longer need "access" permission to a top-level workspace when trying to bind to an APIExport
• We now support quota for cluster-scoped resources

And this is only a sampling of the 160+ amazing commits since v0.7.0!
