Added Microchip Harmony wolfMQTT support (#11)

Added Microchip Harmony wolfMQTT support (see new README.me in IDE/Microchip-Harmony). Adds non-blocking mode "--enable-nonblock" or "WOLFMQTT_NONBLOCK". Combine duplicate code in the examples into examples/mqttexample.c. Added scripts/azureiothub.test. Added ./commit-tests.sh for testing all configurations. Added git pre-commit hook to run commit-tests.sh.

+# Microchip Harmony wolfMQTT client library and examples
+
+This example IDE project is meant to be used from inside the Microchip Harmony directory. The configuration.xml files uses relative paths based on the following:
+
+* Library located in `third_party/tcpip/wolfmqtt`
+* Application examples located in `apps/tcpip/wolfmqtt_client` and `apps/tcpip/wolfmqtt_firmware`
+
+## Using Examples
+
+* Open the example project in your microchip harmony folder under `apps/tcpip/wolfmqtt_client/firmware` or `apps/tcpip/wolfmqtt_firmware/firmware`.
+* Set project as main project (Right-click on project and choose "Set as Main Project"
+* Goto Tools -> Embedded -> MPLab Harmony Configurator
+* Open the default system config.
+* Configure your BSP and Ethernet MAC driver.
+* Click "Save" button and then "Generate Code" button.
+
+## Setting up Harmony
+### To add this library to Harmony
+
+* Copy the entire libraries `wolfmqtt` directory into `third_party/tcpip`.
+* Copy `wolfmqtt.hconfig` into `third_party/tcpip/config`.
+* Add the `wolfmqtt.hconfig` include into `tcpip.hconfig`
+* Add the following lines into `wolfssl.h.ftl`:
+
+```
+<#if CONFIG_USE_3RDPARTY_WOLFMQTT>
+#define WOLFMQTT_NONBLOCK
+
+<#if CONFIG_WOLFMQTT_USE_TLS>
+#define ENABLE_MQTT_TLS
+</#if>
+</#if>
+```
+
+### Adding example apps to Harmony
+* Copy the `wolfmqtt_client` and `wolfmqtt_firmware` directories to `apps/tcpip`
