Disable default stat collection. Update README. about mmock

[jmartin82]

Hi there,

I've never been really concerned about this topic since you can disable the anonymous statics with a flag and you have all the code available to check how mmock is using them (mainly to check if the features are being used or not).

But I see your point.

I will apply the following changes:

1. Update the readme adding all the flags from the CLI.
2. Add specific section about what data is collected by mmock and why
3. Add a line (if it's enabled) below the application banner explaining that mmock is sending statistic information and how to disable it.

Cheers

I understand that you want usage statistics, but shouldn't the default be to not enable this feature instead? Such kind of metrics collection will be problematic in a lot of work places and is an unexpected default to have IMHO, personally I would expect something like this to be an opt-in feature instead of an opt-out.

For me with that is pretty clear what is mmock doing with the statistics, and how to disable it.

And I don't expect anybody concerned about this innocuous metrics.

Thanks!
