Introduce `Process.Shutdown()` and `ProxyManager.Shutdown()`. These two function required a lot of internal process state management refactoring. A key benefit is that `Process.start()` is now interruptable. When `Shutdown()` is called it will break the long health check loop.
State management within Process is also improved. Added `starting`, `stopping` and `shutdown` states. Additionally, introduced a simple finite state machine to manage transitions.
Refactor Process.start()/Stop() logic (#38)
- remove cmd.Wait() call in start(). This seems to conflict with the one
in .Stop(). Removing it eliminated no child errors
- eliminate goroutines in .start() as it no longer required
A panic occurs when a request for an invalid profile:model pair is made.
The edge case is that the profile exists and the model exists but they're
not configured as a pair.
This adds an additional check to make sure the profile:model pair is
valid before attempting to swap the model.
* remove catch-all route to upstream proxy (it was broken anyways)
* add /upstream/:model_id to swap and route to upstream path
* add /upstream HTML endpoint and unlisted option
* add /upstream endpoint to show a list of available models
* add `unlisted` configuration option to omit a model from /v1/models and /upstream lists
* add favicon.ico
Stop Process TTL goroutine when process is not ready (#28)
- fix issue where the goroutine will continue even though the child
process is no longer running and the Process' state is not Ready
- fix issue where some logs were going to stdout instead of p.logMonitor
causing them to not show up in the /logs
- add units to unloading model message
