bdev_ftl: Added FTL bdev functional tests 



This patch introduces functional tests for FTL bdev.

The tests cover various I/O workflows and check data integrity. Several
scripts have been added to test the FTL library:
 * generate_config.sh - prepares configuration scripts for specified
 device
 * restore.sh - tests restoring device's state from the SSD
 * fio.sh - runs tests based on fio and fio_plugin

The tests are run from autotest.sh when the SPDK_TEST_BDEV_FTL flag is
set.
