Fix ExecutionTimeLimit to Enable No Limit - Fixes #115

[PlagueHO]

Pull Request (PR) description
This PR enables setting the ExecutionTimeLimit to no limit (indefinite) by setting the parameter to '00:00:00'. Note: setting ExecutionTimeLimit has to be done differently on Windows Server 2012 R2 and Windows Server 2016/Windows 10, so I've added code to handle them all.

This Pull Request (PR) fixes the following issues:
#115

Task list:

• Change details added to Unreleased section of CHANGELOG.md?
• Added/updated documentation, comment-based help and descriptions in .schema.mof files where appropriate?
• Examples appropriately updated?
• New/changed code adheres to Style Guidelines?
• Unit and (optional) Integration tests created/updated where possible?

@johlju - if you wouldn't mind and have the time would you be able to review?
