Troubleshooting Target Server Administrator's impersonation rights

This test checks if the Administrator user entered in the previous step of the wizard has application impersonation rights. It does so by running the Powershell command, get-ManagementRoleAssignment. If the result is negative, the program tries to add such rights for the Administrator user.
