Security based on SCRAM for kafka backend should also consider plain listener

[rgordill]

Currently, the operator needs trustStoreSecretName to connect using tls.

However, kafka can be configured also with plain connection, but using SCRAM for authentication/authorization. The operator should consider ssl in scram security as optional.

Can I mount the secrets from strimzi user secret? Also is there only support for trustore, do I not need a keystore?

As latest version is jumped to 2.x, it makes no sense this issue anymore.

Would it be possible to use scram with plain listeners now, could you please provide some kind of documentation for it? I am currently running a strimzi kafka with scram-sha-512 authentication on plain listeners and was thinking of using it for apicurio also.
