The current Libpod pkg/spec has become a victim of the better part of three years of development that tied it extremely closely to the current Podman CLI. Defaults are spread across multiple places, there is no easy way to produce a CreateConfig that will actually produce a valid container, and the logic for generating configs has sprawled across at least three packages. This is an initial pass at a package that generates OCI specs that will supersede large parts of the current pkg/spec. The CreateConfig will still exist, but will effectively turn into a parsed CLI. This will be compiled down into the new SpecGenerator struct, which will generate the OCI spec and Libpod create options. The preferred integration point for plugging into Podman's Go API to create containers will be the new CreateConfig, as it's less tied to Podman's command line. CRI-O, for example, will likely tie in here. Signed-off-by: Matthew Heon <[email protected]>

Do we want to give this a name? In case we add extra fields related to healthchecks at some point?

warning: the naming of this might change as well as the location. this is a build on a PR from mheon from last year that proposes a shift from our current approach of creating containers based on the arbitrarily made createconfig. the new approach would be to have a specification that is detached from the podman cli. the spec could then be generated and used to make a container. this theoretically is the beginning of a long-needed refactor involving how we get from the cli -> libpod | apiv2 -> libpod with code re-use and less duplication. the intent is to build the apiv2 container creation based on this approach only. wiring to the podman cli will happen after the fact.
