Introduce View Statistics tab in Management Interface

[24santoshr]

Is your feature request related to a problem? Please describe.
The admin user might want to check the historical usage of the crawler service as well as other components for improvements in the existing framework or for better implementation of new features in the future.

Describe the solution you'd like
A statistics tab in the management screen which could give details about historical data like total number of queries processed for the day, number of failures and errors, its details, time taken to complete the tasks, memory etc so that the admin user can get an idea about the component's usage.

Describe alternatives you've considered
None

Additional context
Also, if possible it will be better to have a log files generated with appropriate messages in the server for each component when it runs so that in case of errors/failures within the application we can check these log file directly and come to know about its cause.

A first step here should be the design of the UI. If we agree on the UI design, then we can move forward.
