feat: update naming conventions for resources and types

Rename 'core' resources to 'meta' (including namespace), introduce new
naming concept:

* internal type name should be `CamelCases.some.cosi.dev`
* resource definition id is `camelecases.some.cosi.dev`
* displayed type name is `CamelCase`
* type aliases are `camelcase`, `camelcases`, `cc`, `ccs`
