consul config file does not notify handler

[bryanlarsen]

If the consul config file changes, it should notify a handler to restart consul.

:+1: on this. I guess i'll just manually run the handler. It may be good to add a handler to reload consul instead of restarting it, if it's only for a configuration change

I would definitely try to avoid restarting automatically especially with Consul Servers. Reload makes sense though

The one problem is that we'd need to be really smart in the handler to determine whether reload or restart is needed given this: https://consul.io/docs/agent/options.html#reloadable-configuration
