Vulnix Dashboard

[dermetfan]

Adds a service that:

1. Runs vulnix once (with configured options, by default just a system scan).
2. Runs vulnix on Nomad jobs by listening to the event stream (if enabled). Disabled by default because it suffices to run this on just one node in the cluster and requires secrets to be configured.
3. Sends the result to Telegraf.

and a dashboard for the results.

Requires changes to bitte-cli to work, see input-output-hk/bitte-cli#28.

Probably my biggest concern is the hardcoded namespaces. Everything else isn't really too major and it's looking really good so far 👍
