Enable authentication for Mongo

[chapmbk]

We have tests that require Mongo authentication to be turned on. This is not possible with the current plugin. I have already added support to my local copy and can send a patch if needed.

            if (authEnabled) {
                commandLinePostProcessor = new ICommandLinePostProcessor() {
                    @Override
                    public List<String> process(
                            final Distribution distribution, final List<String> args) {
                        args.remove("--noauth");
                        args.add("--auth");
                        return args;
                    }
                };
            }

Thanks, this looks like a nice addition. I'll add it in the next version.

Incidentally, how are you adding users to the embedded db once it starts?

We are adding them as part of the test suite set up using the Mongo client(MongoClient.getDb().addUser()). I added that step as part of the plugin initially, but after thinking about it, I thought it fit better as test set up.

I sent you a pull request for this one so you could see the change.
