Allow to totally disable cache

[federicaagostini]

Introduce a new property in order to totally disable cache for the well-known endpoint and scope requested + scope matchers. It can be achieved by setting the environment variable IAM_CACHE_ENABLED=false.

Changes in configuration: if you're using environment variables you won't be affected by any changes. If you're using redis caching mechanism directly through the redis-cache.enabled property you need to upgrade your configuration to:

cache:
  redis:
    enabled: true
