Add ability to specify a shortcut to all collectors

[chris-sanders]

Describe the rationale for the suggested feature.

While moving files to new locations we've added symlinks so that we don't break analyzers while we update file locations to make them available to things like sbctl. However, for users that are accessing files directly the ability to find specific collected information in an easy to access file path can also add value. Making linking an intentional feature rather than a bridge to the new locations would allow these users to find specific files in easy to access locations while we control the path for tools like sbctl.

Describe the feature

The proposal is to add an intentional global collector field to specify a 'shortcut path' which is a link (maybe hardlink?) to the files. This allows a user to make shortcuts to files they care about and allows the troubleshoot project to move files around internally as needed.

Describe alternatives you've considered

We could continue to just put links in legacy paths. That doesn't provide as much control for users and stands to make tech debt if we keep adding links without removing them.
