The PodmanOptionsKey is never used anywhere so it is pointless to add this. Second having several functions to return the same context makes no sense so fold them all into one. Lastly create the context once and always return the same one instead of having to nil check each time. Signed-off-by: Paul Holzinger <pholzing@redhat.com>
