Initialize/tear-down phase differences

When running Rational® Integration Tester tests outside of a performance test, the Initialize and Tear-down phases are each run only once.

However, when a test is run within a performance test, the behavior is slightly different:

• In load-generating tests, the Initialize and Tear-down phases are run once for each test phase on each configured agent.
• In background tests, the Initialize and Tear-down phases run once for each agent because there is no concept of test phases in background tests.
