CoAP component relies on some mbedTLS crypto configuration
options, e.g. DTLS and PSK. These configuration options if
selected, have footprint impact on generic TLS examples like
https_request or https_ota as well.
Footprint of https_request example with/without change is per below:
$ ./tools/idf_size.py new_https_request.map --diff old_https_request.map
<CURRENT> MAP file: new_https_request.map
<REFERENCE> MAP file: old_https_request.map
Difference is counted as <CURRENT> - <REFERENCE>, i.e. a positive number means that <CURRENT> is larger.
Total sizes of <CURRENT>: <REFERENCE> Difference
DRAM .data size: 14796 bytes 14796
DRAM .bss size: 23560 bytes 23680 -120
Used static DRAM: 38356 bytes ( 142380 available, 21.2% used) 38476 -120 ( +120 available, +0 total)
Used static IRAM: 89045 bytes ( 42027 available, 67.9% used) 89045 ( +0 available, +0 total)
Flash code: 554231 bytes 563823 -9592
Flash rodata: 179000 bytes 181224 -2224
Total image size:~ 860632 bytes (.bin may be padded larger) 872568 -11936
This commit moves relevant config options to CoAP specific examples
and also adds some run time warnings if they are kept disabled.

If the CoAP information is to be encrypted, the encryption environment

can be set up in one of two ways (default being Pre-Shared key mode)
|
|
|
|
- Encrypt using defined Pre-Shared Keys (PSK if uri includes coaps://)
|
|
- Encrypt using defined Public Key Infrastructure (PKI if uri includes coaps://)
