Description

PSMDB Operator allows setting the size of cache memory for WiredTiger. The logic is here https://github.com/percona/percona-server-mongodb-operator/blob/main/pkg/psmdb/container.go#L307.

The problem is it doesn't work if only the memory limit is set for the pod because the operator checks for the value of the CPU limit when deciding whether to try putting the cache value or not: https://github.com/percona/percona-server-mongodb-operator/blob/main/pkg/psmdb/container.go#L194.

The operator should check for the memory limit being set, not the CPU limit.
