conntrack: implement save output format
This commit allows dumping conntrack entries in the format
used by the conntrack parameters, aka "save" output format.
This is useful for saving ct entry data to allow applying
it later on.
To enable the "save" output the "-o save" parameter needs
to be passed to the conntrack tool invocation.
