* [CssSelectorBridge] Metadata from social embed (#3602, #3687)
Implement the following metadata sources:
- Facebook Open Graph
- Twitter <meta> tags
- Standard <meta> tags
- JSON linked data (ld+json)
The following metadata is supported:
- Canonical URL (may help removing garbage from URLs)
- Article title
- Truncated summary
- Published/Updated timestamp
- Enclosure/Thumbnail image
- Author Name or Twitter handle
SitemapBridge will also automatically benefit from this commit.

This bridge is a variant of CssSelectorBridge.
