It is often required to run the same test with slightly different test conditions. If we create each test case for each test condition, those test cases are almost same and have code duplication. Such duplication is seen in many of the nvme test cases that set up nvme transport. To avoid the code duplication, introduce a new feature to support test case repetition with different conditions. When a test case implements the function set_conditions(), blktests repeat the test case. When set_conditions() is called without an argument, it returns how many times the test case is to be repeated. Before each test case run, blktests calls set_conditions() with an argument number from 0 to the number of repetitions minus 1. set_conditions() sets up the condition for each test run referring to the argument as the index of the condition to set up. set_conditions() also sets up a short string in the COND_DESC variable. This string is printed to stdout to identify the condition of each run. It is also used as the directory path name to hold result files. Document the usage of set_conditions() in the new script. Separate out shellcheck command line for the new script to avoid a false-positive warning unique to the file.
