Drop Entrypoint and Improve Containerfile

[sjmonson]

• Drop the container entrypoint script as GuideLLM has had native support for its features since Add support for "benchmarking scenarios" #99
• Make containerfile more rebuild friendly based on Add Ubi container #213
• Drop the ENV default scenario as it is confusing to users setting CLI args

Closes: #213

deploy/Containerfile:40

• The default target 'http://localhost:8000' points to localhost inside the container, which likely won't work in most deployment scenarios. This could confuse users who expect the container to work out-of-the-box without understanding they need to override this value.

ENV GUIDELLM_TARGET="http://localhost:8000" \
