[hohwille]

This PR fixes #1640

Implemented changes:

• remove post-install hook from terraform

• implemented suggested mechanism to detect if postInstall* is calling runTool with the initial ToolInstallRequest and skip install in such case.
• track ToolInstallRequest.parent and detect installation loop to prevent further disasters.
