Previously prompt guard was hard coded to require cuda which prevented it from being used on an instance without a cuda support. This PR allows prompt guard to be configured to use either cpu or cuda. Signed-off-by: Michael Dawson <[email protected]>

There was a problem hiding this comment.
can we just check if cuda is available and use that otherwise use CPU? no need for a specific configuration like this to be added.

What does this PR do?
Previously prompt guard was hard coded to require cuda which prevented it from being used on an instance without a cuda support.
This PR allows prompt guard to be configured to use either cpu or cuda.
Closes #2133
Test Plan (Edited after incorporating suggestion)
started stack configured with prompt guard as follows on a system without a GPU
and validated prompt guard could be used through the APIs
validated on a system with a gpu (but without llama stack) that the python selecting between cpu and cuda support returned the right value when a cuda device was available.
ran the unit tests as per - https://github.com/meta-llama/llama-stack/blob/main/tests/unit/README.md
