Config to restart without rebuilding the binary on certain file changes

[joshhunt]

I'm using air for watch + rebuild of an application that reads from a config file on startup. It would be useful if I could configure air to just restart the binary when certain file patterns change.

I'm not sure what the best way to configure this is - my first thought was something similar to docker compose watch where you configure different actions for different paths:

[build]
cmd = "go build -o ./dist/main ."
bin = "dist/main"

[watch]
include_file = "config.ini"
action = "reload"

But this might be overkill for air (considering the only additional action would be reload).

Let me know what you think, and whether you would be open to a PR to contribute this.

I see; I think this is a really good feature, and let's see how to make it easier to configure and how to design it.
