Feature Overview (aka. Goal Summary)  

An elevator pitch (value statement) that describes the Feature in a clear, concise way.  Complete during New status.

This feature is to decide and implement the default credential mode (manual/STS or non-STS) for ROSA Classic. 

Today, the default is non-STS and Warning messages are displayed on ROSA CLI when --sts is chosen to request a cluster that uses STS. Non-STS credential mode has been deprecated for long time now. If we introduce 'ROSA Classic is deprecated as per XCMSTRAT-548, the deprecation message would be undermined by nearly 2-year old deprecation messages of sts/non-sts. 

This feature proposes to switch STS as default on ROSA clusters as per warning deprecation message so the new deprecation messages for ROSA Classic is effective. 

Goals (aka. expected user outcomes)
