Migrate OpenAPI and sample config export to subcommands "export-openapi"
and "export-config".
Also add a "download" subcommand that passes args to the TabbyAPI
downloader. This allows models to be downloaded via the API and
CLI args.

* Model: Fix inline loading and draft key
There was a lack of foresight between the new config.yml and how
it was structured. The "draft" key became "draft_model" without updating
both the API request and inline loading keys.
For the API requests, still support "draft" as legacy, but the "draft_model"
key is preferred.

The loader takes in the "draft" parameter, so map the config model
to that when creating kwargs for initial load.
Also map the old "draft" key to the new "draft_model" key.

Using aiofiles, there's no longer a possiblity of blocking file operations
that can hang up the event loop. In addition, partially migrate
classes to use asynchronous init instead of the normal python magic method.
The only exception is config, since that's handled in the synchonous
init before the event loop starts.

- add models for config options
- add function to regenerate config.yml
- replace references to config with pydantic compatible references
- remove unnecessary unwrap() statements
TODO:
- auto generate env vars
- auto generate argparse
- test loading a model
The config categories can have defined separation, but preserve
the dynamic nature of adding new config options by making all the
internal class vars as dictionaries.
This was necessary since storing global callbacks stored a state
of the previous global_config var that wasn't populated.

Embedding models are managed on a separate backend, but are run
in parallel with the model itself. Therefore, manage this in a separate
container with separate routes.

Use Infinity as a separate backend and handle the model within the
common module. This separates out the embeddings model from the endpoint
which allows for model loading/unloading in core.

These are faster event loops for asyncio which should improve overall

Move OpenAPI export as an env var within the main function. This
allows for easy export by running main.
In addition, an env variable provides global and explicit state to
disable conditional wheel imports (ex. Exl2 and torch) which caused
errors at first.

Async generation helps remove many roadblocks to managing tasks
using threads. It should allow for abortables and modern-day paradigms.
NOTE: Exllamav2 itself is not an asynchronous library. It's just
been added into tabby's async nature to allow for a fast and concurrent
API server. It's still being debated to run stream_ex in a separate
thread or manually manage it using asyncio.sleep(0)

Moving the API into its own directory helps compartmentalize it

Use the module singleton pattern to share global state. This can also
be a modified version of the Global Object Pattern. The main reason
this pattern is used is for ease of use when handling global state
rather than adding extra dependencies for a DI parameter.

Similar to Gradio, fall back to port + 1 if the config port isn't
bindable. If both ports aren't available, let the user know and exit.
An infinite loop of finding a port isn't advisable.

Starlette's StreamingResponse has an issue where it yields after
a request has disconnected. A bugfix to starlette will fix this
issue, but FastAPI uses starlette <= 0.36 which isn't ideal.
Therefore, switch back to sse-starlette which handles these disconnects
correctly.
Also don't try yielding after the request is disconnected. Just return
out of the generator instead.
