Add `astro dbt delete` command

[jeremybeard]

Description

This change adds a new command astro dbt delete, to delete a dbt project bundle from a deployment. This is effectively the inverse of astro dbt deploy. The command effects a delete by creating a new deploy where the reported bundle tarball version is left empty, which Astro understands to mean that the bundle should be deleted from the deployment.

The dbt project to be deleted is automatically inferred from the current working directory, or the project path can be specified, or if the dbt project is not locally accessible the mount path can be provided instead.
