Bug#910746: orca: Support configuration migration

[Samuel Thibault]

Package: orca
Version: 3.30.0-1
Tags: a11y upstream
Owner: bugs at hypra.fr
User: bugs at hypra.fr
Usertags: hypra colomban
Severity: wishlist
Forwarded: https://gitlab.gnome.org/GNOME/orca/issues/21

As reported upstream:

“
For instance, https://gitlab.gnome.org/GNOME/orca/merge_requests/17 changes the orca key binding option content, which would thus need to automatically migrate old configurations to the new option name for capslock.

This is a more general problem which we should implement more generally.
