[Enhancement][zos_data_set] Enhance error messages when not able to create GDGs

[fernandofloresg]

Is there an existing issue for this?

• There are no existing issues.

Enhancement or feature description

Currently there are some conditions that will make a GDG creation to fail. For example, if FIFO is set to true but the system does not have that feature enabled is going to fail, the current error message is ugly and is just a stack trace

The goal of this task is to enhance error messages when GDG creation fails, some scenarios identified are:

• Failure when a GDG name is larger than 35 characters.
• Failure when two parameters are not compatible.
• Failure when FIFO is not enabled on the system.
