add "click-to-define" glossary definitions to harvester UI

[rshewitt]

User Story

In order to better provide definitions of terms in the harvester app, datagov wants glossary terms within the app pages to be clickable and lead to the definition in the glossary.

Acceptance Criteria

[ACs should be clearly demoable/verifiable whenever possible. Try specifying them using BDD.]

• GIVEN a defined term in the glossary
  WHEN that term is present on the page and clicked
  THEN the user is presented the definition of the term in the glossary

Background

Security Considerations (required)

[Any security concerns that might be implicated in the change. "None" is OK, just be explicit here!]

Sketch

• replicate what's on resources
• relavant code
• may need to add munging prior to regex match ( e.g. "records_with_ckan_id: ", what's on the page, doesn't match its corresponding regex /(\bRecords With CKAN ID\b)(?![^<]*>|[^<>]*<\/)/i, what's on the glossary.
• can also just change what's on the page instead
