Add `enable` option to docs

[lukehesluke]

Hi,

I've found the enable option (introduced here: #158) to be useful in order to run automated tests that don't actually send events to Segment. However, had to do a bit of digging to find it.

Perhaps it should be in the docs? I'd be happy to do it myself if that helps 😊

You mean in the docs here: https://segment.com/docs/connections/sources/catalog/libraries/server/node/
We add that ourselves. But thanks for offering help.

We'll add it soon. Thanks

Update section in this location: https://segment.com/docs/connections/sources/catalog/libraries/server/node/#configuration

Was:
var analytics = new Analytics('YOUR_WRITE_KEY', {
flushAt: 20,
flushInterval: 10000
});

Is:
var analytics = new Analytics('YOUR_WRITE_KEY', {
flushAt: 20,
flushInterval: 10000,
enable: false
});

Recommended Text block update:
enable Boolean. Enable (default) or disable flush. Useful when writing tests and you do not want to send data to Segment Servers

Hi, I don't see this in docs yet. is this safe to rely on to disable segment in localhost, for example?

[pbassut]

@davidbielik On the enable property? Can't tell because at least the java library don't have such a thing. You can rely it on it on this version for sure. If we ever remove it we'll do a breaking change note. So don't worry.
