Macros
#define	AWS_IOT_MQTT_HOST   ""
	Customer specific MQTT HOST. The same will be used for Thing Shadow.
#define	AWS_IOT_MQTT_PORT   8883
	default port for MQTT/S
#define	AWS_IOT_MQTT_CLIENT_ID   "c-sdk-client-id"
	MQTT client ID should be unique for every device.
#define	AWS_IOT_MY_THING_NAME   "AWS-IoT-C-SDK"
	Thing Name of the Shadow this device is associated with.
#define	AWS_IOT_ROOT_CA_FILENAME   "aws-iot-rootCA.crt"
	Root CA file name.
#define	AWS_IOT_CERTIFICATE_FILENAME   "cert.pem"
	device signed certificate file name
#define	AWS_IOT_PRIVATE_KEY_FILENAME   "privkey.pem"
	Device private key filename.
#define	AWS_IOT_MQTT_TX_BUF_LEN   512
	Any time a message is sent out through the MQTT layer. The message is copied into this buffer anytime a publish is done. This will also be used in the case of Thing Shadow.
#define	AWS_IOT_MQTT_RX_BUF_LEN   512
	Any message that comes into the device should be less than this buffer size. If a received message is bigger than this buffer size the message will be dropped.
#define	AWS_IOT_MQTT_NUM_SUBSCRIBE_HANDLERS   5
	Maximum number of topic filters the MQTT client can handle at any given time. This should be increased appropriately when using Thing Shadow.
#define	SHADOW_MAX_SIZE_OF_RX_BUFFER   AWS_IOT_MQTT_RX_BUF_LEN+1
	Maximum size of the SHADOW buffer to store the received Shadow message.
#define	MAX_SIZE_OF_UNIQUE_CLIENT_ID_BYTES   80
	Maximum size of the Unique Client Id. For More info on the Client Id refer Acknowledgments.
#define	MAX_SIZE_CLIENT_ID_WITH_SEQUENCE   MAX_SIZE_OF_UNIQUE_CLIENT_ID_BYTES + 10
	This is size of the extra sequence number that will be appended to the Unique client Id.
#define	MAX_SIZE_CLIENT_TOKEN_CLIENT_SEQUENCE   MAX_SIZE_CLIENT_ID_WITH_SEQUENCE + 20
	This is size of the the total clientToken key and value pair in the JSON.
#define	MAX_ACKS_TO_COMEIN_AT_ANY_GIVEN_TIME   10
	At Any given time we will wait for this many responses. This will correlate to the rate at which the shadow actions are requested.
#define	MAX_THINGNAME_HANDLED_AT_ANY_GIVEN_TIME   10
	We could perform shadow action on any thing Name and this is maximum Thing Names we can act on at any given time.
#define	MAX_JSON_TOKEN_EXPECTED   120
	These are the max tokens that is expected to be in the Shadow JSON document. Include the metadata that gets published.
#define	MAX_SHADOW_TOPIC_LENGTH_WITHOUT_THINGNAME   60

#define	MAX_SIZE_OF_THING_NAME   20
	The Thing Name should not be bigger than this value. Modify this if the Thing Name needs to be bigger.
#define	MAX_SHADOW_TOPIC_LENGTH_BYTES   MAX_SHADOW_TOPIC_LENGTH_WITHOUT_THINGNAME + MAX_SIZE_OF_THING_NAME
	This size includes the length of topic with Thing Name.
#define	AWS_IOT_MQTT_MIN_RECONNECT_WAIT_INTERVAL   1000
	Minimum time before the First reconnect attempt is made as part of the exponential back-off algorithm.
#define	AWS_IOT_MQTT_MAX_RECONNECT_WAIT_INTERVAL   8000
	Maximum time interval after which exponential back-off will stop attempting to reconnect.
