Enable contract testing on OIDC protected resources on Quarkus testing tools

[patoulatchi]

Reason/Context

The context of the feature request has been discussed here:
https://github.com/orgs/microcks/discussions/1379

Description

Support of creation of valid bearer tokens against the OIDC Quarkus devservice tools (keycloak) to be able to contract test API which are authenticated.

Implementation ideas

The keycloak related information (url/port/client/secret/username/password) could be provided by the test implementer in the TestRequest builder. Something similar to this below:

TestRequest testRequest = new TestRequest.Builder()
      .serviceId("My API:1.0.0-SNAPSHOT")
      .runnerType(TestRunnerType.OPEN_API_SCHEMA.name())
      .testEndpoint("http://host.testcontainers.internal:" + quarkusHttpPort)
      .withKeycloakUrl("http://host.testcontainers.internal:" + keycloakPort).withClient("myOidcClient").with....
      .build();

You can now use constructs as:

// Issue a TestRequest with OAuth2 context.
TestRequest testRequest = new TestRequest.Builder()
   .serviceId("API Pastries:0.0.1")
   .runnerType(TestRunnerType.OPEN_API_SCHEMA.name())
   .testEndpoint("http://good-impl:3002")
   .timeout(2000L)
   .oAuth2Context(new OAuth2ClientContext.Builder()
      .clientId("myrealm-serviceaccount")
      .clientSecret("ab54d329-e435-41ae-a900-ec6b3fe15c54")
      .tokenUri("http://keycloak:8080/realms/myrealm/protocol/openid-connect/token")
      .grantType(OAuth2GrantType.CLIENT_CREDENTIALS)
      .build())
   .build();
