Dean Troyer 1686dc54f0 Help/docs cleanups: marker, limit, ip-address metavars
Cleanup help strings and docs for clarity and to keep things consistent:
* --limit metavar should be <num-resource> to indicate what is being counted
* --marker metavar should be <resource> or <resource-id> to indicate the
  type of value being specified
* <*-ip-address> metavars should be just <ip-address> as there is no difference
  in format between fixed and floating IPs
* Move all occurances of '(name or ID)' to end of help text
