Slack username not included in message

[arvidgloot]

With default config of fluxcloud, and the username env var set to something other than Flux, I can't see the username being changed in Slack channel. My env config:

- name: SLACK_USERNAME
  value: "Cool cluster"
- name: SLACK_URL
  value: "https://hooks.slack.com/services/XXXXXXXXX"
- name: SLACK_CHANNEL
  value: "#my-channel"
- name: SLACK_ICON_EMOJI
  value: ":sync:"
- name: GITHUB_URL
  value: "https://github.com/my-repo"
- name: LISTEN_ADDRESS
  value: ":3032"

Or maybe even more important, how do I access the username in the templating created in #12?

@justinbarrick Slack username and icon is absolete nowadays, stated here:

You cannot override the default channel (chosen by the user who installed your app), username, or icon when you're using Incoming Webhooks to post messages. Instead, these values will always inherit from the associated Slack app configuration.

It would be nice to be able to access through the template though.
