Add instructions for MQTT broker setup on Windows for coreMQTT demos (#360)

Browse Source 
This adds instructions for setting up a local Mosquitto broker on Windows for use with the coreMQTT demos. There are different instructions for mutual auth, server auth, and plaintext.

It is our recommendation to always use strong mutual authentication in any Internet of Things
application. Instructions below are for setting up a local Mosquitto broker that supports
TLS server-only authentication for use with this MQTT demo.
1. Generate certificates with OpenSSL.
a. Download and install [Git For Windows](https://git-scm.com/download/win).
Most of you may already have this installed. Git For Windows provides an
OpenSSL binary for generating certificates.
b. Open PowerShell and enter the following commands to generate TLS certificates:
i. cd "C:\Program Files\Git\usr\bin" # If Git is installed elsewhere, update the path.
ii. mkdir $home\Documents\certs
iii. .\openssl.exe req -x509 -nodes -sha256 -days 365 -newkey rsa:2048 -keyout $home\Documents\certs\ca.key -out $home\Documents\certs\ca.crt
iv. .\openssl.exe req -nodes -sha256 -new -keyout $home\Documents\certs\server.key -out $home\Documents\certs\server.csr
v. .\openssl.exe x509 -req -sha256 -in $home\Documents\certs\server.csr -CA $home\Documents\certs\ca.crt -CAkey $home\Documents\certs\ca.key -CAcreateserial -out $home\Documents\certs\server.crt -days 365
2. Download Mosquitto from https://mosquitto.org/download/
3. Install Mosquitto as a Windows service by running the installer.
4. Go to the path where Mosquitto was installed. The default path is C:\Program Files\mosquitto.
5. Update mosquitto.conf to have the following entries and don't forget to substitute your Windows username:
port 8883
cafile C:\Users\%Substitute Windows username%\Documents\certs\ca.crt
certfile C:\Users\%Substitute Windows username%\Documents\certs\server.crt
keyfile C:\Users\%Substitute Windows username%\Documents\certs\server.key
tls_version tlsv1.2
6. Start the Mosquitto service.
More details about running Mosquitto as a Windows service can be found at
https://github.com/eclipse/mosquitto/blob/master/readme-windows.txt and
https://github.com/eclipse/mosquitto/blob/master/readme.md
7. Verify that Mosquitto server is running locally and listening on port 8883
by following the steps below.
a. Open PowerShell.
b. Type in command `netstat -a -p TCP | findstr 8883` to check if there
is an active connection listening on port 8883.
c. Verify that there is an output as shown below
`TCP 0.0.0.0:8883 <HOST-NAME>:0 LISTENING`
d. If there is no output on step c, go through the Mosquitto documentation
listed above to check if the setup was correct.
8. Make sure the Mosquitto broker is allowed to communicate through
Windows Firewall. The instructions for allowing an application on Windows 10
Defender Firewall can be found at the link below.
https://support.microsoft.com/en-us/help/4558235/windows-10-allow-an-app-through-microsoft-defender-firewall
After running this MQTT example, consider disabling the Mosquitto broker to
communicate through Windows Firewall for avoiding unwanted network traffic
to your machine.
9. After verifying that a Mosquitto broker is running successfully, update
the config `democonfigMQTT_BROKER_ENDPOINT` to the local IP address of your
Windows host machine. Please note that "localhost" or address "127.0.0.1"
will not work as this example is running on a Windows Simulator and not on a
Windows host natively. Also note that, if the Windows host is using a
Virtual Private Network(VPN), connection to the Mosquitto broker may not work.
10. In the certs folder of your Documents, you will find a file called `ca.crt`.
Copy its contents to `#define democonfigROOT_CA_PEM`. Keep in mind that it
must include the PEM header and footer and be formatted in this manner:
#define democonfigROOT_CA_PEM \
"-----BEGIN CERTIFICATE-----\n" \
"...base64 data...\n" \
"-----END CERTIFICATE-----\n"
11. Update the config `democonfigdisableSNI` to `( pdTRUE )`. It needs to be
configured this way because the local MQTT broker will only have an IP
address but not a hostname. However, SNI (Server name indication) should
be enabled whenever possible.

It is our recommendation to always use strong mutual authentication in any Internet of Things
application. Instructions below are for setting up a local Mosquitto broker that communicates
over plaintext for use with this MQTT demo.
1. Download Mosquitto from https://mosquitto.org/download/
2. Install Mosquitto as a Windows service by running the installer.
3. Start the Mosquitto service.
More details about running Mosquitto as a Windows service can be found at
https://github.com/eclipse/mosquitto/blob/master/readme-windows.txt and
https://github.com/eclipse/mosquitto/blob/master/readme.md
4. Verify that Mosquitto server is running locally and listening on port 1883
by following the steps below.
a. Open PowerShell.
b. Type in command `netstat -a -p TCP | findstr 1883` to check if there
is an active connection listening on port 1883.
c. Verify that there is an output as shown below
`TCP 0.0.0.0:1883 <HOST-NAME>:0 LISTENING`
d. If there is no output on step c, go through the Mosquitto documentation
listed above to check if the setup was correct.
5. Make sure the Mosquitto broker is allowed to communicate through
Windows Firewall. The instructions for allowing an application on Windows 10
Defender Firewall can be found at the link below.
https://support.microsoft.com/en-us/help/4558235/windows-10-allow-an-app-through-microsoft-defender-firewall
After running this MQTT example, consider disabling the Mosquitto broker to
communicate through Windows Firewall for avoiding unwanted network traffic
to your machine.
6. After verifying that a Mosquitto broker is running successfully, update
the config `democonfigMQTT_BROKER_ENDPOINT` to the local IP address of your
Windows host machine. Please note that "localhost" or address "127.0.0.1"
will not work as this example is running on a Windows Simulator and not on a
Windows host natively. Also note that, if the Windows host is using a
Virtual Private Network(VPN), connection to the Mosquitto broker may not work.
