MPS update device information

[matt-primrose]

When a device connects to MPS or when I pull device data from AMT, I want MPS to update the data in the MPS database so that the next time I pull device data from MPS, if the device is currently disconnected, I can still get the device data stored in the database.

Acceptance Criteria:

• Data should include: AMT Version, AMT Build, AMT SKU, AMT Branding String, AMT Provisioning Mode, IP Address, Last Updated. 1302
• When an AMT device connects to MPS, last connected date is updated. 1153
• When an AMT device disconnects to MPS, last disconnected date is updated. 1153
• When a Devices call is made and the AMT device is not connected, the information returned is the latest information stored in the database 1499
• Verification tests must confirm the successful execution of the commands.
• Last heartbeat on device object stored in db. 1153
• When get device api (api/v1/devices/{guid}) is called add additional timestamp info to the returned data. 1153
• Update Azure Deployment 248
