Controls the current execution parameters and manages API configurations
Usage:
c = Config() # initializes the argument parser

# you can then access the Services and APIs like
c.s3_config
All the configurations available as cmd line options, when included, will
override the configurations in the config.json file.
Configurations are split between:
1. "secrets" containing API keys for generating services - not kept in memory
2. "execution" containing specific execution configurations
