Add a function that tests can use to skip when the metadata device isn't large enough. I thought we needed to avoid enospc in a particular test, but it turns out the test's failure was unrelated. So this isn't used for now but it seems nice to keep around. Signed-off-by: Zach Brown <zab@versity.com>
