VA-15956: Add VBA facility service region facilities with taxonomies

[maxx1128]

Summary

VBA Regional Facilities can have several facilities connected with them as being within their region or "regional subsections." Each subsection also has several taxonomies associated with them to describe better and organize them for users.

This pull request adds the subsections with their taxonomies to the regional facility query. They can then be added to the VBA Regional Facility page.

Looks right to me. Do we want to ask @swirtSJW to double check?
