If fs.s3a.create.performance is set on a bucket - All file overwrite checks are skipped, even if the caller says otherwise. - All directory existence checks are skipped. - Marker deletion is *always* skipped. This eliminates a HEAD and a LIST for every creation. * New path capability "fs.s3a.create.performance.enabled" true if the option is enabled. * Parameterize ITestS3AContractCreate to expect the different outcomes * Parameterize ITestCreateFileCost similarly, with changed cost assertions there. * create(/) raises an IOE. existing bug only noticed here.
