Alert Manager Route Module

[sj-williams]

Background

Proposal:

A user CP module for managing Slack Alertmanager Route configs

As part of removing our dependency on git-crypt for secrets currently managed in infrastructure repo, we should look at viability of offloading alert manager configs to users themselves. This might look something like:

• user creates kubernetes secret containing webhook, channel, severity
• module is called, passing k8s secret as input
• trigger the templating of new config into the existing config data (would need to look at decoupling existing yaml from the Prometheus chart values)

Benefits:

• users manage alertmanager routes themselves (less work for us)
• clean up components infrastructure (much less terraform read / verbose pipeline output / faster plan and applies
• one less thing managed via git-crypt
