Motivation for changes:

Wanted to have a notification go out when something is grabbed and another go out when it's available, but didn't want to be notified that it was grabbed, only that it was available; without creating two separate channels.

Detailed changes:

• Added new property called silent onto discord notifier plugin.
• Check if silent is true, set property flags onto web_hook object with the suppress notification bitfield set.

Config usage if relevant (new plugin or updated schema):

notify:
  task:
    message: <message>
    via:
      - discord:
          web_hook_url: <web_hook_url>
          silent: true
