Remove hapi dependencies

fhir core validation and cli validation are depending on:

<dependency>
    <groupId>ca.uhn.hapi.fhir</groupId>
    <artifactId>hapi-fhir-structures-r4</artifactId>
    <scope>test</scope>
</dependency>
<dependency>
    <groupId>ca.uhn.hapi.fhir</groupId>
    <artifactId>hapi-fhir-validation-resources-r4</artifactId>
    <scope>test</scope>
</dependency>

• removing the structures dependency causes https://github.com/hapifhir/org.hl7.fhir.core/blob/master/org.hl7.fhir.validation/src/test/java/org/hl7/fhir/validation/tests/InstanceValidatorR4Test.java to fail. As this is an hapi specific test this could/should be moved to the hapi repo.
• fhir validation-resources should be part of core.

@jamesagnew are you ok with this?

[jamesagnew]

Yeah, those were added only for unit tests and I'm not opposed to removing them given that the unit test doesn't work currently.
