Deprecation of feature to add comments/share/like to individual media content within articles

[everton-rosario]

This deprecated all the acessor methods to the properties of shares, comments and likes.

• Removes the properties from media elements: Image and Video
• Adapts test cases to not expect the data-feedback property to be set
• Keeps code as non-breaking change
• Removes any rule setting to read/interpret the data-feedback property
• Adds @deprecated annotation to all methods affected
