V2 podman command

[jwhonce]

• New Domain Objects
• New Engine access bindings
• Podman V2 command using above

In V2 to find all logic regarding a command follow path, for example:
cmd/podmanV2/images/list.go or cmd/podmanV2/containers/container.go

Some commands are really aliases, podman images vs podman image list. The aliasing command may reference the cobra.Command{} of the source command. Other cross references should be avoided.

Note:

1. To allow podman V1 and V2 to live in the same repository. Types or code may be duplicated for a time. New build tags are packages are used to segregate the code as well.
2. PodmanV2 will allow for two modes of building, in support of:
   • remote clients using ssh tunnels
   • local services using either ssh tunnels or the embedded library

TODO:

• root/rooless configuration
• finish all domain objects/types
• api handlers ported to domain objects
• bindings ported to domain objects
• v1 business logic copied into v2 commands
