Relay CRC request for telemetry to the user on the first start

[dgolovin]

Starting from CRC 1.21.0 it requests to allow or not allow telemetry at the first start. This stops crc starting process until yes or no input sent back to input stream for request. CRC starter should be aware of it and ether allow user to type yes or no, or translate this request to vs code Information message with Yes and No buttons.

Current implementation runs setup in terminal and that allows to enter yes or no in response to request, but in future releases vscode UI should be user to present request to the user.
