Interactive console

This is an epic. It would be amazing if there was the ability to send requests using this interface.

This could be a new tab under each endpoint and when selected it provides:

• Ability to set headers (required header key should be read from the Swagger)
• Ability to set URL parameters (likewise)
• Ability to set the body (be awesome if we could validate while we type, but that's a stretch goal)

When sending the request, it should then echo back:

• The response headers
• The response body
