+Namespace Format testcase :-
+
+ 1. Create, attach, detach, delete primary namespace and
+ extract the supported format information from default namespace:-
+ - List of the supported format.
+ - List of Metadata Size per format. Based on this we calculate
+ data protection parameter at the time of namespace.
+ - List of LBA Data Size per format.
+ 2. Use the collected information and iterate through each supported
+ format:-
+ - Create namespace.
+ - Attach namespace.
+ - Run IOs on the namespace under test.
+ - Detach namespace
+ - Delete Namespace.
