Add support for flags in DatastoreEmulatorContainer

[eddumelendez]

Datastore can start with additional flags such as --consistency 1.0
which is recommended for testing.

See https://cloud.google.com/sdk/gcloud/reference/beta/emulators/datastore/start

Thanks for your PR @eddumelendez and also thanks for reviewing and merging it, @kiview :-)

one thing: why do you add comments containing methods wrapping the actual method? I first thought you missed to delete it, but these pattern is present in all of the GCP tests and in a similar way also in other tests. Looks like this is some testcontainers magic :-) Maybe you can explain it in a brief manner? Would love to learn something new :)

Hi @bennetelli 😃
These are our markers for referencing code snippets in our docs, by using https://github.com/rnorth/mkdocs-codeinclude-plugin.

@kiview @eddumelendez do you know when these changes will be released? :) looks like they are not part of the latest patch release

[kiview]

@bennetelli They will be part of the next testcontainers-java release, which we plan to do soon. Until then, you can always use the latest snapshot version through Jitpack 🙂
