Monorepo plugin

[apaleslimghost]

pretty barebones right now, but it works!

• just exports a task. if you want to run commands in your workspace packages, run that task at the toplevel, and it will run the same command in the workspace

  example

  .toolkitrc.yml

  commands:
    test:local: WorkspaceCommand

  packages/something/.toolkitrc.yml

  commands:
    test:local: Cypress # only needed in this package

  npx dotcom-tool-kit test:local in the root runs test:local in packages/something, which runs Cypress

• refactors some stuff in the core to expose some internals needed for the monorepo task

• rudimentary error handling and logging, i would like to go through this with a fine tooth comb when i get chance

opened as a draft as i want to discuss whether it's worth merging in its current state or if it needs fleshing out a bit more

still to do:

• proper error handling and logging
• tests!
• try migrating cp-content-pipeline to it 😬
• documentation (plugin + high level monorepo workflow overview)

i'm very happy that this is so simple! though the proof is in the cp-content-pipeline pudding...
