Feature/add main env

[cotts]

Related issue: #9

• Add Generic env config to be used by Mocha and Cypress.
• Add prettier
• Update sample file
• Update gitignore
• Updated all files with prettier config

I also run cypress and mocha locally to test the new environment config.

@kmanaseryan I've tried to run the package using several configuration formats without success. (I read the cypress documentation and some articles.

It looks like even if we set the env format inside this package when it's loaded as a dependency, the environment configuration set inside this module is ignored. It will always require cypress.json.

Probably we will need to use another approach to solve this.

@kmanaseryan, I've removed the dotenv config and set mocha to run using cypress.json environment config.
