Add list-features, --enable-features, & --disable-features

[Chaseshak]

What's changing?

• Adds public facing commands for customers to interact with customer facing feature flags.
• Note This interface is a little clunky atm, but not many customers use --features atm. There is follow-up work to investigate storing this in a credentials file and/or as env variables.

How's this tested?

• Specs
• Running some commands locally:
  • Note You will need to pull the latest docker image before running these commands
  • dotnet run --project src/ActionsImporter/ActionsImporter.csproj -- list-features
  • dotnet run --project src/ActionsImporter/ActionsImporter.csproj -- dry-run circle-ci -o tmp/circle --source-file-path tmp/config.yml --circle-ci-project rails-demo --disable-features=workflow-concurrency-option-allowed actions/cache
    • This should result in an output file that comments out the caching actions syntax

Here's a circle CI config you can use for testing:

version: 2.1

orbs:
  ruby: circleci/ruby@1.1.0
  node: circleci/node@2

jobs:
  build:
    docker:
      - image: cimg/ruby:2.7.5-node
    steps:
      - checkout
      - ruby/install-deps
      # Store bundle cache
      - node/install-packages:
          pkg-manager: yarn
          cache-key: "yarn.lock"

workflows:
  version: 2
  build_and_test:
    jobs:
      - build

Closes github/valet#5714
