LocalDatastoreHelper should accept a custom port to start the emulator. #4933
Description
Hello.
I'm using Spring libraries to operate with the GCP products and I found a issue with the datastore emulator helper.
Unfortunately the class LocalDatastoreHelper has a hardcoded way to find the port to start the emulator and doesn't accepts a custom port.
To ensure datastore testing with all spring libraries I will need to set the port based on my own configuration and this will also make easly the usage of the helper itself.
I was wondering about a new constructor adding the support for a custom port.
See spring discussion here.
