Include '--title' option support for gnome-terminal 'windows' and 'tabs' in RHEL7.2

Issue

• Include 'Title' option support for gnome-terminal windows and tabs similar to what was available in older versions of gnome-terminal as available in RHEL prior to the RHEL7.2 release.

• Previous versions of gnome-terminal prior to RHEL7.2 allowed titles to be set in terminal windows and tabs with the --title option. It was also possible to set the title on a tab by performing a right-click on a tab and selecting the 'Set Title...' option.

• In addition, there was also a preserve title feature that could be set via the gnome-terminal "Profile Preferences" --> "Title and Command" --> "Title: Keep initial title" selection. This was useful in conjunction with --title in many circumstances.
