Description

Merges in changes to upstream filters. See https://github.com/bloom-housing/bloom/pull/1359/files for changed filed.

• Adds generic filters query param to listings.controller.ts
• Adds generic filters handling to listings.service.ts
• Adds an enum of filter types to listing.dto.ts, so we can handle specific filters differently
• Changes upstream filter param from ListingFilterParam[] to ListingFilterParam to match its actual type.

I opened issues to for some TODOs in this PR:

• Make addFilter generic so we can contribute upstream #202
• Update querystring format so param ordering doesn't matter #210
