In lava job definition,  boot action can use "connection-namespace" to indicate use previous namespace's connection.Does deploy action have such as "deploy-namespace" to indicate to use previous deploy image?
For example in an application scenario, it need to sequential execution two phases  pipeline(deploy,boot,test), it can be solved by define two namespace in job definiton.
When run it executed in serial as :  phase1(namespace1)  deploy->boot->test   -> phase2(namespace2) deploy->boot->test. 
If phase2 deploy images(kernel,dtb,rootfs)  are exactly same as phase2 deploy  images,how to speed up phase2 deploy execution?  I guess if deploy action have such as "deploy-namespace" to indicate previous deploy,then phase2 deploy process can be pass.
