Slack request: Option to configure minimum notification pushing time gap.

[jnash10]

Currently,
A 'content updated' notification is pushed to Slack even in the time one takes to frame one sentence after the other in Gitbook.
This causes many notifications to pop up on other people's devices who're subscribed to the channel.

It'd be awesome if there were an option to change the minimum time gap between Slack pushes to control the workflow better.

The integration is helpful to keep your team updated on your progress without pinging them.
I'd love to contribute to the development of this feature if required.

Thanks!
