Add optional CGW_ENV attribute to the configuration

[hectorgomezv]

Summary

This is motivated by the necessity of having different auth cookie configurations per environment, so the CGW needs a configuration value specifying the current environment at runtime.

Changes

• Add optional CGW_ENV attribute to the configuration.
• Moves the applicationPort attribute along with the new one to an application node in the configuration schema.
