Rake task to check readiness for two connections
As a follow up for: #387905 (closed)
We can considering adding some script/rake task to allow the customers to check if they are ready for upgrading to two connections, which will be enabled by default in %16.0.
This can be done by checking the number of current connections to the database, and comparing it with the max_connections. And recommend increasing it if needed.
