feat(errors): Add YAML definitions for new features columns

[cmanallen]

Adds YAML definitions for the new features columns and index. These columns will allow us to search for errors by feature flag.

TODO:

• Needs killswitch definition for: events_features_hash_map_enabled. Where is this defined?

This is set in the runtime config for Snuba.

@evanh I had to update the replacer test coverage. Hopefully this is fine or do I need to update elsewhere? The diff might be hard to read. The change is just adding the flag columns to the query.

cc @untitaker since I think you worked on this too?
