This replaces _unsupported_qemu_io_options and check for support of
current cache mode, and allow to provide a default if user didn't
specify.

fef9c19139 qemu-iotests: Quote $TEST_IMG* and $TEST_DIR usage
A lot of image filename and paths are used unquoted.  Quote these to
make sure that directories / filenames with spaces are not problematic.

ff42308f30 qemu-iotests: Do not execute 052 with -nocache
Test 052 uses qemu-io -s which will result in bdrv_open trying to create
a temporary snapshot file in /tmp. However, since O_DIRECT and tmpfs
do not work well together, disable this test for -nocache.

Check that writes to an image opened with BDRV_O_SNAPSHOT do not modify
the underlying image file.
