Add the ability to view the configurations, steps, and other variables which reference a specific variable. This can be exceptionally useful when understanding the impact of changing a variable's name, value, or format.

Currently the only way to do this effectively is interrogate the database backup and look for vars.getValue('VAR_NAME').

A few ways would be to inspect the audit log for this syntax for a string, or to scan the "variables" section of builds and provide a "last used" or "used in" link, which results in the list of jobs which have made use of the variable.
