Refactor: Enable and Disable Keycloak Security Configuration by Profile

[rehammuzzamil]

We can do a bit of RnD to enable and disable the Keycloak Security Configuration class by passing a param in application.yml or by using Spring/Maven Profiling.

Reason:
To avoid failing existing unit tests that do not pass an Authorization header.
Reference: #8

Possible Solutions:

• Use the configuration only for a profile add @Profile to the class
• Enable it by the property, add @ConditionalOnProperty to the class.
