Mix of camel and snake case

[jtaleric]

The majority of our config file is camel case, should we default to camel case vs mixing it up?

orion/utils/orion_funcs.py

Line 64 in 8d7515f

metric_of_interest = metric['metric_of_interest']

[shashank-boyapally]

Will change to camel case

Same happens with some file names @shashank-boyapally, in python, everything is snake_case except class names
