Subject: podman generate spec

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
