Review comment:
Do you mean the priority? If so, suggest to change precedence to priority to
make it more clear:
`The priority is as following: 1. the configuration
'python.client.executable' defined in the source code; 2. the environment
variable PYFLINK_EXECUTABLE; 3. the configuration 'python.client.executable'
defined in flink-conf.yaml`
