Our sarama client has kerberos FAST negotiation turned on by default, but there are KDCs that can't handle FAST negotiation and will fail. There is an option to configure this on the sarama client, but we didn't expose it anywhere, so users couldn't get to it. This just adds an additional auth parameter to AuthConfig to expose that configuration option so users who need to shut off FAST are able to do so. Signed-off-by: John Kyros <[email protected]>

This:
kerberosDisableFASTfield to the kafka scaler metadata, which can be used to disable sarama's/gokrb5's FAST negotiation for kerberos connectionskerberosDisableFASTfield in the AuthConfigWhich will let a user disable FAST as part of their Kerberos configuration.
I'm not attached to any of the naming here, I just want the plumbing, right now we just can't manipulate this at all. 😄
