Add Project Catalog description and tags from source repository

[daalfa]

When adding a new project catalog with the following command:
spring project-catalog add --name name --url url --description description --tags tag1 tag2

The correct information is displayed with spring project-catalog list, but only if project-catalog was explicitly added with description and tag.

Expected behaviour:

when adding a new project catalog without tag and description it should fetch from the remote repository project-catalog.yml

Current limitation: There is no catalog specific property in project-catalog.yml for tags and description.
