Description

Allow the user to provide a top-level requirements.sh file (it could be named something else), in which they can install system dependencies.

Motivation

Some dependencies must be installed via apt or via conda

Things to check

• Would this support running in a conda environment?
• chmod +x if necessary

Things to document

• Users would need to run apt-get update before apt-get install
• Building your own image will lead to faster API startup times
