feat: Interception Scripts to add extra authorization during client authentication

[pujavs]

Requirement:

Currently jans-config-api uses basic authentication, requirement is to use an interception scripts which can enable custom business logic for authentication.
For example, a customer may want to pass an access token with a custom claim, like {"role": "manager", "infrastructure": "prod"}
The script should read that information from the access token, and then write custom rules about whether to allow or deny the client authentication.
