Implement templates for email service

[adriaaaa]

Description

Fides will need to be able to send html content from Fides to your email service (like mailgun). This ticket is to cover the work needed for fides to create and send html content through

Assumptions

• advanced configurations of fonts/styles will be handled in the future, so we can hard code the style based on the mocks we have.

Acceptance Criteria

1. Decide on templating lib/engine. Good options:
   http://mustache.github.io/#demo- not exclusive to python
   GitHub - pallets/jinja: A very fast and expressive template engine. - python exclusive

• Consider that we'll eventually will have UI to configure things such as colors, subject line, body text, font style, font size
• Consider how we can support preview mode in future

2. Demonstrate that we can send an MFA email through mailgun using a template where the MFA code gets populated dynamically into the template on the back-end.
3. Ensure that the template logic is modular enough so that many more templates can be added in the future.

Refinement Notes:

• design to create basic email for MFA sending
• No other personalized content to be sent in the email since it puts us at risk for scammers (needed until captcha).
• Sanitize our inputs from the FE
