fix pod volume passing and alter infra inheritance

the infra Inherit function was not properly passing pod volume information to new containers
alter the inherit function and struct to use the new `ConfigToSpec` function used in clone
pick and choose the proper entities from a temp spec and validate them on the spegen side rather
than passing directly to a config

resolves #13548
