Return title fields as a list

Podman is attempting to split the headers returned by the ps
command into a list of headers. Problem is that some headers
are multi-word, and headers are not guaranteed to be split via
a tab. This PR splits the headers bases on white space, and for
the select group of CAPS headers which are multi-word, combines
them back together.
