Send submissions workflow notifications to Slack

[wang-arthur]

Currently, the managing editor handles all correspondence with authors and reviewers via email, and communicates updates manually to the editors via Slack.

• [ ] First, add a temporary solution
• [ ] Later, create a reusable plugin for PKP OJS
  • First pass
  • Use webhooks) for sending notifications to a single Slack channel
  • No customization (plugin hardcodes which OJS hooks trigger Slack webhook notifications)
  • Later versions
  • Use API key instead of Webhook
    • More customization, send to multiple or different channels (& users?)
  • Customize who gets what notifications

Create a Slack app to make this integration two-way? (Notifications from OJS -> Slack, actions from Slack -> OJS)
