Add EAP version into UMB message for 7.7

The UMB message which is sent to QE doesn't contain EAP version. That is crucial parameter needed for acceptance test (for checking versions in the EAP).

This information will be part of the UMB payload, which is composed as follow:

• Components
• Containers
• Non-Productised/Unmanaged Payload
  • EAP version
  • Spring Boot 2 version

There will be a separate object inside the UMB message (Non-Productised/Unmanaged Payload)

Action Items:

• QE needs to process this new message to get information which are not directly provided by the build but which are inherited from the BOM
• PROD will provide UMB message example
