Update the device connection details and optionally run connection test.

Updates the connection details of a device. If the skipValidation parameter is set to false (default) it will run a test for manually added devices to see whether it can establish a connection with the global url. If there is a new global host or port provided, it will run the test with the new global host/port, otherwise it will test the current global url. If this test fails it will not update ANY connection detail provided in the ConnectionDetailUpdate object and will throw a validation error. If the test is succesful (when skipValidation is false) and the settings are changed correctly it will return OK.
