V2 Enable rootless

* Enable running podman V2 rootless
* Fixed cobra.PersistentPreRunE usage in all the commands
* Leveraged cobra.PersistentPreRunE/cobra.PersistentPostRunE to manage:
  * rootless
  * trace (--trace)
  * profiling (--cpu-profile)
  * initializing the registry copies of Image/Container engines
* Help and Usage templates autoset for all sub-commands
