Let API tests run without report_portal_integration, using dynamic loading

- Removed @Step annotations, as pointcut is hardcoded in com.att->
  .automation.common.report_portal_integration.aspects.StepAspects

- Introduced ReportPortalListenerDelegator that loads com.att->
  .automation.common.report_portal_integration if available

- Optimized and organized dependencies

- Upgrade maven-assembly-plugin to resolve "Java heap space" error.
