user story

As an OpenShift cluster admin,

I want the option to build my OS image first, then roll it out to a MachineConfigPool at a later time

so that I can ensure that my Containerfile syntax is correct as well as ensure that any customizations I've made work as I intended.

Alternatively, the current paused pool mechanism could theoretically be used for this as well. A cluster admin would need to pause the pool before doing an on-cluster build for that pool.

Done When:

• Either the explicit annotation or reusing existing paused pool mechanism path is chosen or a currently-unknown mechanism is chosen.
• The chosen mechanism is implemented.
