Improve group and project level package api

As per discussion in !18860 (merged):

To use the current api in the new vue component for package list we need to improve the current functionality

Both projects and groups api:

• Add sorting on all the exposed parameters
  1. name
  2. version
  3. type
  4. created date
  5. project path ( for group )
• Add created date
• Add _path dictionary that contains
  1. details_path
  2. destroy_path

On groups api

• add project id
• add project path / namespace ( group + subgroups + project name )
