* Minor changes

* Include Cypress support files in published package

* Added CLI

… with support for custom configurations (which Cypress does not currently support by default):

  * Loads cypress.json from @grafana/e2e as a base config (via a custom Cypress plugin)
  * Sets default values for project-level Cypress files (tests, etc)
  * Optionally loads a cypress.json from the current working directory as overrides

* Updated lockfile
