With the move of a the composite aggs code to the aggregations plugin, this effectively renders the aggregation plugin as an Extensible plugin ( since x-pack-core uses the composite aggs code directly ). The X-pack-core plugin then requires to "extend" the aggregation plugin, so that the classloader hierarchy is setup correctly at runtime. Following all this, lang-painless is now transitively required (by the aggregations plugin ), for all plugins extending x-pack-core, so we need to move it as an explicit "extends" from plugins that extend from x-pack-core
…t when building named xcontent registry. These tests use composite aggregation and because this aggregation moved to aggregation module as part of this change these tests need this tweak.

Do we use ExtensiblePlugin yet?

Oh wild. So they get the extension transitively through x-pack-core -> aggregations -> lang-painless? That seems odd. Does x-pack-core extend aggregations just so it can see it or something else? I'm not entirely clear on when you'd do what with the extension mechanism.
