We use a jenkins environment that run in kubernetes, the all platform and jenkins is managed by another corporate team. Jenkins have a cloud configuration that specifies a custom jnlp image.

While using declarative pipelines one needs to specify the jnlp confguration on every agent definition on all projects, would be a great improvement if the plugin fetches the jnlp configuration from jenkins kubernetes cloud defintiion before setting there own.

With this approach, jenkins can have the default configuration and there is no need to replicate this on the declarative pipeline of each project.
