Manager to reuse reserved id #272
Description
We can improve the manager to reuse a reserved id instead of reserving new ids every single run.
Simple manual way of doing it is to provide an id in the builder/program config, then the manager can check if this id is free (no program deployed) and if it is, use it.
Automated way would be to save it in some sort of cache (file), and if the deployment errored, next deployment will use the id in cache, if it succeeded we can remove id from cache.
