V2 YAML seeding

What does this MR do and why?

The second iteration for the AwesomeCo Demo Data Seeder -

To make the seeder more usable, especially for those not familiar with ruby, a YAML format has been devised to allow seeding.

This YAML format is a 1:1 translation of what can be passed into FactoryBot.

Example

seed.yaml.erb

labels:
  - name: Test
    color: "#FFFFFF"

# will produce: FactoryBot.create(:label, name: 'Test', color: '#FFFFFF')

issues:
  - name: Issue
    description: |
      # This is markdown
    traits:
      - confidential

# will produce: FactoryBot.create(:issue, :confidential, name: 'Issue', description: '# This is markdown')
