Support for Discord webhooks
Description
Hey! Would be possible to support Discord webhooks? They're different from GlitchTip Webhooks, but they're well documented
See links for documentation:
https://support.discord.com/hc/en-us/articles/228383668-Intro-to-Webhooks
https://discord.com/developers/docs/resources/webhook#execute-webhook
Also, i've made a little proxy from Glitchtip webhooks to Discord webhooks: https://github.com/ThallesP/glitchtip-to-webhook-discord
I've made that in 20 minutes, so I don't know if it's the best in describing the errors.
Proposed Solution(s)
I can make the change if you guys point me at the right direction (where to do it and how to separate it from the currently webhook implementation).
