Argument parsing issue for nngproxy

[pmf]

Describe the bug
The nngproxy subcommand of nanomq_cli does not work for me due to an argument parsing issue. I have to revert the change in e9fe4b1 for nng_proxy.c (i.e. initialize idx as 2 again) to make nanomq_cli nngproxy work.

Expected behavior

(After reverting e9fe4b1 for nng_proxy.c)

# ./nanomq_cli nngproxy pub0 --mqtt_url mqtt-tcp://127.0.0.1:1883 --dial tcp://localhost:3327 -t foo
unable to connect tcp://localhost:3327 Connection refused!
# that's OK, and it works when I have a corresponding listener

Actual Behavior

(Without reverting e9fe4b1 for nng_proxy.c)

# ./nanomq_cli nngproxy pub0 --mqtt_url mqtt-tcp://127.0.0.1:1883 --dial tcp://localhost:3327 -t foo
NNG url is invalid.

To Reproduce
See command lines above.
