• add the regular copyrights with your name and the vHive community
• use logrus instead of the default log.
• move config variables to a JSON file. that file should have a hierarchy of parameters (e.g., kubernetes, contained, etc) just like you structured files in scripts/configs.
• move scripts/configs to configs/vHive

[ustiugov]

• Please describe where to find which parameters throughout config JSON files. Make sure there are no parameters that replicate each other (e.g., those that can be derived based on the k8s version).

please increase verbosity in logging
