This first commit creates a section in
a subproject settings that shows all
inherited group vars available to the
project.

Add styles and origin column with group name

Added styling to align with mockup and a
new column to display the origin of where
the group variable is coming from.

Add support for nested subgroups

There is the ability to have a nested
subgroup under a group. I've added the
ability to naviagate to that groups ci
variables settings page

Add conditionals for ruby variables

If a project doesn't exist in a group
but instead a personal namespace, the
code will break since we don't have a
check for that. Also added a changelog

Fix linting errors

Adjust styling for mobile and desktop

A certain class needed was adding border
top on mobile for keys. I removed so it
didnt break layout. Also removed padding
that bunched up borders

Add test coverage for new feature

Remove un-needed code in multiple files

Remove class selector that is not used
and remove variable declartion that is
not used. As well as remove un-needed
conditional in Haml file.

Fix linting errors

Move inherited vars in UI

section in project settings. Also add another
use case and more test coverage.
