implement a new command `podman generate spec` which can formulate a json specgen to be consumed by both the pod and container creation API. supported flags are --verbose (default true) print output to the terminal --compact print the json output in a single line format to be piped to the API --filename put the output in a file --clone rename the pod/ctr in the spec so it won't conflict w/ an existing entity Signed-off-by: Charlie Doern <cdoern@redhat.com>
