Is there a way to tune the Nomad server parameters within the server stanza like heartbeat_grace, etc. using the HTTP API?
Example:
I went through the HTTP API docs here: HTTP API | Nomad by HashiCorp
… but couldn’t find a way to PUT those values using the HTTP API.
If the HTTP API does exist, what would be the commandline way of tuning this? 
Use case: I have bootstrapped my cluster with a heartbeat_grace of 5m, but now want to tune it down to 2m.
