Description

The configuration option `taskmanager.cpu.cores` is meant for internal usages only and should not be advertised to users atm.

However, the following logs could be printed when Flink runs in local environment, which not only leaks the option to the users, but may also mislead them to explicitly set it.

"The configuration option taskmanager.cpu.cores required for local execution is not set, setting it to xxx".

The log comes from `TaskExecutorResourceUtils#adjustForLocalExecution`.
