[entropy.client/equo] add "equo query mimetype" support

User can now search for packages providing a specific mimetype,
which means, telling the user what application can be used to
open his/her files.
Add two now entropy.client.interfaces.Client methods:
  - list search_installed_mimetype(string mimetype)
  - list search_available_mimetype(string mimetype)
