This PR adds end 2 end testing scenarios for Mars OTC ELR reports moving through the UP.
These scenarios test when reports with the Mars OTC ELR topic

• Are sent in HL7 and received as HL7 and FHIR.
• Are sent in FHIR and received as FHIR.
• When invalid HL7 items are present in the report, these are filtered out.

Test Steps:

1. Run ./gradlew testend2endup
2. Verify that all scenarios pass.
   1. For scenario "Sending HL7 Report, Receiving HL7/FHIR (mars-otc-elr); Invalid HL7 Items Filtered Out":
      • A FHIR report should be sent to MARS_OTC_ELR_FHIR_B_E2E
      • An HL7 report should be sent to MARS_OTC_ELR
      • Both sent reports consist only of one item
      • One item has been filtered out with the message "Item 1 in the report was not valid. Reason: HL7 was not valid at OBX[1]-19[1].1"
   2. For scenario "Sending FHIR Report, Receiving FHIR (mars-otc-elr)":
      • A FHIR report should be sent to MARS_OTC_ELR_FHIR_A_E2E
