SEO meta tag contentful section

[frizman21]

Assumes that every page include a title.

• [ ] App should automatically populate the canonical link on all pages, by default - what do we think the URL to this page is.
• [ ] provide a field for everything in this list https://github.com/kpumuk/meta-tags#allowed-options-for-display_meta_tags-and-set_meta_tags-methods
• can assume that application.rb fires display_meta_tags function call and include this gem meta-tags in the gem file
• consider which of these are common answers on every page - create object structure to represent this complexity - require CMS implementor to only provide page specific details
