feat: allow hostname override for notifiers (#994)

Browse source 
* feat: allow hostname override for email notifier

As it currently stands all notifiers utilise `os.Hostname` to populate their titles/subjects.

When utilising Docker with a bridged network if you set the hostname for a container to an external DNS hostname Docker's internal DNS resolver will override said hostname for all containers within the bridged network.

This change allows a user to specify what hostname should be represented in the email notifications without having to change the `os.Hostname`.

* feat: allow custom hostname for all notifiers

* docs: adjust notification hostname flag
