Nathan Ross 569cd162d3 tests: refactor conventional TestScenario usage
Updates to individual integration tests

  - use proposed conventional approach to beginning tests

  - use new convenience functions for using fixtures

  - use new names for TestScenario

Updates to integration test modules

  - add proposed conventional module-level functions

Updates to test/common/util.rs

  - rename TestSet, and its methods, for semantic clarity

  - create convenience functions for use of fixtures

  - delete convenience functions obsoleted by new conventions
