To clarify, index types are not being removed. What has been removed is the ability to have an index with more than 1 type. This means titlesuggest and ttmserver should need no direct changes, as they already meet this requirement afaict. The content/general indices contain multiple types and need this new field.

We might also want to look into how to handle id overlap between types. We currently use mediawiki page id's for most things, but i could see deletes to a page type reordering with indexing to the archive type,

The metastore index also needs a new type field.

We've decided to split archive into it's own index, and move namespace into metastore. As such only metastore needs the new type field now.
