GATEWAY_SECURITY_MODE environment variable
This release introduces the GATEWAY_SECURITY_MODE environment variable,
which simplifies the configuration process by splitting out what manages authentication/authorization (valid values: KAFKA_MANAGED or GATEWAY_MANAGED) from how it should be managed (still set in the GATEWAY_SECURITY_PROTOCOL environment variable).
This is a non-breaking change, still supporting existing configurations whilst encouraging a new approach.
This change also allows for the deprecation of the ACL_ENABLED environment variable. Whilst we still support it, we strongly encourage users to use the GATEWAY_SECURITY_MODE environment variable.
Please see How to: Migration Guide to Security Mode for more details.
