16.10.1 16.11.1 16.12.1 16.12.1s 16.12.2s Gibraltar-16.10.1

Description (partial)

Symptom:
If webUI fails to render a page or soem elements in a page, it might return errors like "nil response from wsma" which in itself does not identify any root cause. 

The ask is to make a show command available with drop counters if this error or other errors are encountered. Also the drop counters need to be granulated down to specific reason codes
Ex: nil response from wsma can be 
a) nginx crsh
b) temporary connection loss
c) all vty lines in use 
etc

Similar granularity for websocket reason code.

Idea is to run this CLI multiple times to identify which dropr eason code is incrementing and use it for troubleshooting/root causing/fixing issue.

Please consider also addign a historic view of timestamps and types of failure seen for the wholistic view of the system.

Conditions:
webUI failing to render the page or some elements on a page.
