Add the ability to configure webhook receiver URLs for additional external webhooks. This enhancement will be as simple as possible, there are no plans to support all alertmanager configuration features. The implementation will consider a later expansion.

Example spec:

service_type: alertmanager
service_id: xyz
user_data:
   default_webhook_urls:
   - "https://foo" 
   - "https://bar" 

The alertmanager.yml file will now contain a 'default' receiver configuration where these additional URLs will be added. A second route will contain the already existing receiver configuration for the Dashboard.

The resulting alertmanager.yml file will look like:

# See https://prometheus.io/docs/alerting/configuration/ for documentation.

global:
  resolve_timeout: 5m

route:
  receiver: 'default'
  routes:
    - group_by: ['alertname']
      group_wait: 10s
      group_interval: 10s
      repeat_interval: 1h
      receiver: 'ceph-dashboard'

receivers:
- name: 'default'
  webhook_configs:
  - url: 'https://foo'
  - url: 'https://bar'
- name: 'ceph-dashboard'
  webhook_configs:
  - url: 'https://localhost:41211/api/prometheus_receiver'
