Remove mockwebserver dependency in favor of wiremock

[magicDGS]

These changes are to simplify the testing of the different client implementation that will be done with #141, as the current custom system does not take into account different ordering of the query-params that might happen with a different implementation.

Using wiremock and its standard structure will be easier to onboard people and also moves forward to remove the dependency on okhttp even for testing.

Also, with these changes we are moving forward on using the capabilities of quarkus to inject dependencies and to enable property-based configuration that on test can be overriden with resources/profiles.

First step for #141
