Resolve "Seat Link Service"

What does this MR do?

For the self hosted instances, we need to capture every day the total maximum count the instance had from the date the license has started till the previous day.

For the same reason, we are running a cron job picking a random number from 1 - 30 so that job in different instances but same time zone gets distributed. This job would calculate the max count till the previous day and POST it to the customers application along with the license key.
