135804 jkaabimofrad: APPSREPO-35, APPSREPO-118: Added tests for reset password service and REST API.
- Added a utility class (EmailUtil) to work with MailActionExecutor in test mode
- Added a new workflow task responsible for sending the reset password confirmation email (per peer review)
- Changed the reset-password endpoint to return a 202 response for an inactive workflow or invalid workflow id, key or mismatched user
- Some other minor changes as the result of adding tests
- Also, fixed tests failures by changing the reset password workflow definition target namespace URI.
