This is a pretty important requirement. The streaming response type is
an AsyncGenerator while the non-stream one is a single object. So far
this has worked _sometimes_ due to various pre-existing hacks (and in
some cases, just failed.)
Also introduce a gross hack (to cover grosser(?) hack) to ensure
non-stream requests don't send back responses in SSE format. Not sure
which of these hacks is grosser.
This is just like `local` using `meta-reference` for everything except
it uses `vllm` for inference.
Docker works, but So far, `conda` is a bit easier to use with the vllm
provider. The default container base image does not include all the
necessary libraries for all vllm features. More cuda dependencies are
necessary.
I started changing this base image used in this template, but it also
required changes to the Dockerfile, so it was getting too involved to
include in the first PR.
Working so far:
* `python -m llama_stack.apis.inference.client localhost 5000 --model Llama3.2-1B-Instruct --stream True`
* `python -m llama_stack.apis.inference.client localhost 5000 --model Llama3.2-1B-Instruct --stream False`
Example:
```
$ python -m llama_stack.apis.inference.client localhost 5000 --model Llama3.2-1B-Instruct --stream False

I have only tested these models:
* `Llama3.1-8B-Instruct` - across 4 GPUs (tensor_parallel_size = 4)
* `Llama3.2-1B-Instruct` - on a single GPU (tensor_parallel_size = 1)
Before using `--security-opt label=disable`, check that SELinux is
enabled. Otherwise, the option is not relevant.
This fixes errors on Mac.

While rebuilding a stack using the `docker` image type and having
`LLAMA_STACK_DIR` set so it installs `llama_stack` from my local
source, I noticed that once built, it just used the image build cache
and didn't pull in changes to my source.
1. Install in editable mode (`pip install -e`) for dev purposes.
2. Mount the source into the container for `configure` and `run` so
that the editable install works.

When I ran `llama stack configure` for my `docker` based stack on my
system using podman + SELinux (CentOS Stream 9), The `podman run`
command failed due to SELinux blocking access to the volume mount.
As a simple fix, disable SELinux label checking.
