Backports the following commits to 1.x:

* Move _meta section back inside mappings, in legacy templates. (elastic#1186) 

This fixes an issue introduced by elastic#1156, discovered in elastic#1180. Composable templates support `_meta` at the template's root, but legacy templates don't. So we're just putting it back inside the mappings for legacy templates.

This also fixes missing updates to the component template, after the introduction of wildcard in elastic#1098.
