Network status alert for clinical data entry

About the feature : 

This feature when configured alerts the users if they've lost internet connectivity or if the server is down.

This is important because if the user tries to save when the network is down the save would fail and the user might lose data. 

When the system loses the connectivity with the Bahmni Server the following message would be shown. 

The client side system would keep polling for the server and will keep displaying the offline status till the connection is not re-established. 

When the connection comes back, the following alert will be displayed.

     "config": {
	      "showNetworkStatusMessage": true,
