Description

Steps to reproduce:

1. Compile minifi-cpp with no CoAP support
2. Configure C2 with nifi.c2.agent.protocol.class=CoapProtocol
3. Start MiNiFi C++

Expected behavior:

Print an error message to stderr, produce a log message with log level of at least error and exit. Alternatively, produce a log message with log level of at least warning and continue execution without C2.

Actual behavior:

No output on stderr.
Error message logged with log level info.
Segmentation fault in C2Agent.cpp:329, trying to dereference C2Agent::protocol_, but it's null.
