### What needs to get done The Project model needs to parse and validate a top-level `components` keyword containing a list of `Component` pydantic models. The schema is: ```yaml components: <name>: type: "test" summary: ... description: ... version: ... ``` Rules: - component names are unique - component names adhere to the naming convention for namespaced partitions (lowercase alphabetical characters and hyphens, cannot start or end with a hyphen) - component type is `test` - summary is a string with the same naming convention as the top-level `summary` keyword - description is a string (same as the top-level `description`) - version is an optional field with the same naming convention as the top-level `version` keyword Snapcraft also needs a new function in the Project module called `get_component_names() -> List[str]`. It should return a list of component names. Later, this will be used to create a list of partitions to pass to the `LifecycleManager`. ### Why it needs to get done To support components in snapcraft
