Some of the test cases in nvme test group do the exact same test for two blkdev types: device type and file type. Except for this difference, the test cases are pure duplication. It is desired to avoid the duplication. When the duplication is avoided, it is required to control which condition to run the test. To avoid the duplication and also to allow the blkdev type control, introduce a new configuration parameter NVMET_BLKDEV_TYPES. This parameter specifies which blkdev type to setup for the tests. It can take one of the blkdev types. Or it can take both types, which is the default. When both types are specified, the test cases are repeated twice to cover the types. Also add the helper function _set_nvme_trtype_and_nvmet_blkdev_type(). It sets up nvmet_blkdev_type variable for each test case run from NVMET_BLKDEV_TYPES. It also sets nvme_trtype from NVMET_TRTYPES. When NVMET_BLKDEV_TYPES and NVMET_TRTYPES are set as follows, the test case with _set_nvme_trtype_and_nvmet_blkdev_type in set_condition() hook is called 2 x 3 = 6 times.
