Add issue templates

[AndersBennedsgaard]

It should be as quick and easy as possible to leave our feedback.

Therefore, we should make use of github issue templates. (useful information here)

We should probably have separate templates for code bugs, feature requests, security issues, etc. The templates should be as simple as possible to follow.

An example of a bug template (placed in .github/ISSUE_TEMPLATE/bug.yaml):

name: Bug Report
description: File a bug report
title: "[Bug]: "
labels: ["bug", "triage"]
projects: ["trifork/48"]
assignees:
  - trifork/cheetah-core-team
body:
  - type: markdown
    attributes:
      value: |
        Thanks for taking the time to fill out this bug report!
  - type: input
    id: contact
    attributes:
      label: Contact Details
      description: How can we get in touch with you if we need more info?
      placeholder: ex. email@example.com
    validations:
      required: false
  - type: textarea
    id: what-happened
    attributes:
      label: What happened?
      description: Also tell us, what did you expect to happen?
      placeholder: Tell us what you see!
      value: "A bug happened!"
    validations:
      required: true
  - type: dropdown
    id: area
    attributes:
      label: What area does the problem affect?
      multiple: true
      options:
        - Local development
        - Deploy to cluster
        - Other
  - type: textarea
    id: logs
    attributes:
      label: Relevant log output
      description: Please copy and paste any relevant log output. This will be automatically formatted into code, so no need for backticks.
      render: shell
  - type: checkboxes
    id: terms
    attributes:
      label: Code of Conduct
      description: By submitting this issue, you agree to follow our [Code of Conduct](https://example.com)
      options:
        - label: I agree to follow this project's Code of Conduct
          required: true
