* Agents authenticate with NSAPI
* /submit with better auth
- also adjust agent run script to authenticate, even in parallel
* /request better authentication
- moved agent API calls to Client struct
* Replay protection
* Fix testrun cleanup bug
- introduce a new column last_assigned which is different than
created_at so that stale testruns get cleaned up based on
last_assigned
- created_at is still useful for determining the "oldest" testrun
to be picked up
* Uniform request authentication
* Suppress ts-rs serde warnings
* Update cargo version
* All agents use the same key
- remove assigned_agent column
- remove logic which would stop agents with
the same key to connect
- as a safety measure, add cap to total no. of agents
