Description

Say I have a user interface where a URL is provided: coap://example.org/sensor or coaps://example.org/sensor. Currently, when gcoap_dtls is compiled in gcoap_req_send() does not provide me any capability to honor that URL input. It just selects DTLS (so always assumes coaps://, as far as I can tell).

Steps to reproduce the issue

Try to send an unencryptet CoAP request using gcoap_req_send() with gcoap_dtls compiled in.

Expected results

The CoAP request is unencrypted and sent over a UDP sock.

Actual results

The CoAP request is always encrypted and sent over a DTLS sock.
