🔥🔧 Remove environment variables specific to hardware conf

[gkumbhat]

Changes

Following environment variables are quite specific to the hardware and platform vllm-spyre is being run on. Therefore, ideally we should rely on the "reasonable" defaults for this from underlying stack rather than changing those defaults in vLLM.

Env variables:

• FLEX_UNLINK_DEVMEM
• FLEX_RDMA_MODE_FULL

👋 Hi! Thank you for contributing to vLLM support on Spyre.
Just a reminder: Make sure that your code passes all the linting checks, otherwise your PR won't be able to be merged. To do so, first install the linting requirements, then run format.sh and commit the changes. This can be done with uv directly:

uv sync --frozen --group lint --active --inexact

Or this can be done with pip:

uv pip compile --group lint > requirements-lint.txt
pip install -r requirements-lint.txt
bash format.sh

Now you are good to go 🚀

LGTM, but we need to decide which Dockerfile we want to keep as a single source of truth.

LGTM, 🤞 that soon we'll have public docs to link out to about these so that users actually know how to set them when they're needed
