Testing Procedures:

1. Add project template:
   a. FILE > NEW > C PROJECT
   b. Type project name and select IoT AWS, IoT Azure or IoT GCP.
2. Update MQTT credentials and TLS certificates.
   a. (Optional) Update MQTT credentials in iot_config.h
   b. Update TLS certificates in Certificates folder.
3. (Optional) Update IP address, gateway, netmask in main.c. [System now gets a valid DHCP address]
4. Compile and run.

Notes:

When testing, replace the contents of Certificates folder (dummy certificates) with the contents
of the Certificates_Test folder (test certificates to connect with my AWS/GCP/Azure accounts).

Known Issues:

1. Creating the project template takes a long time
   (Excluding files for compilation takes a long time. Check if can exclude folders instead.)
