Add component filtering based on key

[LeoColman]

Describe the problem

Even though I can

• Set the string to read-only
• Fastlane changelogs are lowest-priority shown to translators

I still have some problems I can't address:

• Read-only strings won't allow translators willing to translate changelogs to do it, reducing overall translatability
• Bundling both in the same component doesn't allow vision of true translation of the app -- Changelogs are not exactly part of the app and shouldn't count to the % translated of the language
• Changelog files (if left write-enabled) taint translation percentage of more-valuable app details

Describe the solution you would like

I'm not sure what exactly to suggest, but the only thing I can think of is getting this screen:

and adding an exclusion (i.e. "Exclude files matching fastlane/metadata/android/changelogs/*") filter, which would mean filtering depending on key. It should probably behave similarly to how current Languages filter work.

Describe alternatives you have considered

• Using the bulk edit addon

As explained above, this is more of a workaround than a final solution to the problem.

Just found out #8084, but closing that in favor of this as the description is way better here.

PS: #1993 might also be related.

To implement this:

• Add Key filter field to the Component model
  • Add validation to force it empty for bilingual files which do not use keys
  • Include it in component creation forms
  • Include it in settings form
  • Include it in the API serialization
  • Add documentation for the field with some examples for the filters
• Implement actual filtering in Translation.check_sync
• Add tests to see the filtering is applied
  • Initial creation of a component with a filter should filter out strings
  • Adding a filter to an existing component should remove filtered out strings
  • Removing a filter from existing component should bring back filtered out strings
