Description
Readiness probe for mongos in Percona's Operator runs listDatabases.
It looks like a suboptimal solution for a cases where there are lots of databases (ex. 100k) in the cluster as it takes lots of time to retrieve them all.
We need to think about:
1) Why listDatabases was picked
2) Come up with a better solution
