Add mastodon as new notification channel

[developer-guy]

Summary

Mastodon is free and open-source software for running self-hosted social networking services.

Motivation

Mastodon will become one of the leading social networks in the industry. So, there is considerable interest in moving out from Twitter to Mastodon these days.

Proposal

There is a Go SDK of the Mastodon API¹, so we can add Mastodon as a new notification channel.

Similar work has been done in the GoReleaser project².
