warnings from recent versions of terraform

[mtesch-um]

When I look at the log, I see a large number of warnings about non-computed attribute like

2021-12-21T14:22:02.999-0100 [WARN]  Provider "registry.terraform.io/brainly/redshift" produced an in
valid plan for redshift_user.xyz, but we are tolerating it because it is using the legacy plugin
 SDK.
    The following problems may be the cause of any confusing errors from downstream operations:
      - .superuser: planned value cty.False for a non-computed attribute
      - .syslog_access: planned value cty.StringVal("RESTRICTED") for a non-computed attribute
      - .valid_until: planned value cty.StringVal("infinity") for a non-computed attribute
      - .connection_limit: planned value cty.NumberIntVal(-1) for a non-computed attribute
      - .create_database: planned value cty.False for a non-computed attribute

I dont know if these are actual problems, but they make it less nice to read the logs :-)
