Jhon Honce 8dd26289bf Fixes --remote flag issues
* --remote, --url and --identity are now anchored to podman command.
  Subcommands should no longer have issues
* TraverseChildren now set to V1 expectations
* Latest flag now has helper function. Now has consistent usage.
* IsRemote() uses cobra parser to determin if --remote is given
* Moved validation functions from parser pkg to validate pkg
*

Fixes #6598
Fixes #6704
