SCRAM-SHA-1-PLUS + SCRAM-SHA-256-PLUS + SCRAM-SHA-512-PLUS + SCRAM-SHA3-512(-PLUS) supports

[Neustradamus]

After:

• SCRAM-SHA-1
• SCRAM-SHA-256
• SCRAM-SHA-512

Can you add supports of :

• SCRAM-SHA-1-PLUS
• SCRAM-SHA-256-PLUS
• SCRAM-SHA-512-PLUS
• SCRAM-SHA3-512
• SCRAM-SHA3-512-PLUS

You can add too:

• SCRAM-SHA-224(-PLUS)
• SCRAM-SHA-384(-PLUS)

"When using the SASL SCRAM mechanism, the SCRAM-SHA-256-PLUS variant SHOULD be preferred over the SCRAM-SHA-256 variant, and SHA-256 variants [RFC7677] SHOULD be preferred over SHA-1 variants [RFC5802]".
