feat: add the ability list and restart deployments

[colesnodgrass]

• fix https://github.com/airbytehq/airbyte-internal-issues/issues/9582
• add a abctl local deployments sub command
  • by default will list all the deployments
  • if passed --restart=[deployment name], will restart the provided deployment
• add k8stest package
  • moved mockK8Client (from the existing tests) to MockClient in this package
  • follows a similar model that the package dockertest uses
• update the default k8s.Client to be injectable (in kong)
  • this enabled me to write tests for the deployment sub-command
  • also adds the ability to write tests easier for other sub-commands (not in this PR)
