FI-2337: add disableDefaultResourceFetcher to fhir_resource_validator.cliContext defaults

[dehall]

Summary

Adds the new HL7 validator wrapper cliContext setting disableDefaultResourceFetcher to our cliContext defaults. This depends on hapifhir/org.hl7.fhir.core#1526 but can be merged in before that because the hl7 validator wrapper ignores any unrecognized options. (confirmed against the production instance at https://validator.fhir.org/ )

Full details on this setting are available on the ^ linked PR, but it prevents fetching of unknown profiles and extensions, for example when a resource reports a profile in meta.profile that is not part of the IG under test. The Inferno validator wrapper does not fetch these profiles so this setting makes the hl7 wrapper match the inferno wrapper in that regard.

Testing Guidance

Here are the usual notes on using the hl7 validator wrapper:

• enable the hl7_validator_service in docker-compose.background.yml and nginx.background.conf
• In your test suite, use fhir_resource_validator instead of validator and make sure it points to the hl7 wrapper. An easy place to do this is in the demo suite dev_suites/dev_demo_ig_stu1/demo_suite.rb:

    fhir_resource_validator do
      url ENV.fetch('FHIR_RESOURCE_VALIDATOR_URL')
      exclude_message { |message| message.type == 'info' }
    end

How confident are you that this will end up being the name for this option?

[dehall]

Good point - I'm fairly confident but not 100% sure on that. The name has already changed once. With that in mind, maybe we should leave this PR open until the other PR is officially merged
