Make your bash prompt informative

I am working with multiple cloud environments, terraform projects, git repositories and kubernetes clusters. So, it hard to keep in mind which environment is set in a given time. To minimise risk of deploing staff in undesired environment I utilised bash prompt to inform me what is current environement I work with.
