MAINTAINERS.md needs to be properly slugified at all tiers

[vantuyls]

Is your feature request related to a problem? Please describe. Currently, the cookiecutter CLI asks for basic information about the repository. There is an opportunity to collect more information about maintainers and add more variables tocookiecutter.jsons to populate MAINTAINERS.md.

Describe the intended behavior The CLI tool asks a series of questions and collects responses from the user. The responses are then populated into MAINTAINERS.md upon repository creation.

Describe the solution you'd like Some variables that can be added include but are not limited to:

• Maintainers: Name, github username, role (reviewer, approver, maintainer)

Steps to completion:

• Review current cookiecutter questions and MAINTAINERS.md across all tiers.
• Identify potential variables to add. Consider whether there are tier-specific variables. Get list approved by team.
• Add new variables to cookiecutter.json and templates. Populate fields accordingly during repository creation.

06/17:

• Met and discussed. Nick will take MAINTAINERS.md, and Brandon will take CODEOWNERS.md
• goal: finish this ticket before EoW!

Idea: Have two lists: "Current maintainers" and "Emeritus (aka retired) maintainers" (see if this can be automated!, maybe have occasional reminders)

note-to-self: go over potential variables to add with team via slack on friday (can't during meeting since unavailable)

Did some research on JINJA2 and CLI automation, may require some automation to help streamline the maintainers process. Will need to ask during meeting about how cookiecutter.json works with MAINTAINERS.md in more detail.
