* Along with this comes the testing strategies that make this work
* The repository model where plugins can be stored and cataloged
* Bridging this into an OSGi system: if this could be done then we can basically take over p2

- dealing with processing of input and adapting GAVs before searching i.e. plugin groups in Maven and default searching

node ready. This is required because previously, if there were errors of communication with the cloud-provider on the cloud-controller-manager, nodes may have been declared Ready without having this field or the zone labels, and the information was never reconciled. The providerID and the zone labels are required for integrations like loadbalancers to work correctly. Users still can opt-out to this new behavior by setting the feature flag OptionalProviderID in the cloud-controller-manager. ([#12333...
