create simple-wlcg-schema, simple-wlcg-defaults, simple-wlcg-meta-info

[maany]

Description

The base-schema created in #4 described a generic schema that has to be satisfied by all the site_level_config_file.yaml's. wlcg or not. For the WLCG use-case of the SIMPLE Framework, we have to extend the base-schema and add schema elements for wlcg-specific components. This new schema will be called wlcg-schema.

The following new sections must be added to the base-schema:

• voms_config
• site
• supported_virtual_organizations

Resources

• supported_virtual_organizations is a list of vo objects. Examples of the vo_object can be seen here: https://github.com/WLCG-Lightweight-Sites/simple_grid_site_repo/blob/master/site_level_configuration_defaults.yaml#L9

• The details for the site element can be inferred from:
  https://github.com/WLCG-Lightweight-Sites/simple_grid_yaml_compiler/blob/master/tests/resources/complete_config.yaml#L15

• For voms_config, refer to this site_level_config_file:
  https://github.com/WLCG-Lightweight-Sites/wlcg_lightweight_site_ce_cream/blob/master/augmented_site_level_config_file.yaml#L305
  The object is a list of voms_configurations. Each voms_configuration is composed of voms_fqn (string), pool_accounts (list of objects of type pool_account) and vo.

Expected Outcome

3 new files in the repo, namely,

1. simple-wlcg-schema.yaml
2. simple-wlcg-defaults.yaml
3. simple-wlcg-meta.yaml
