Adding a helper library that wraps fio execution. This is the basic initial check-in that implements the runners, configs, and a single WriteFiles helper. It should be enough to unblock subsequent tasks that will use fio to generate data sets for kopia snapshot verification. More helper workloads can be added as needed. In this implementation the tests will all skip from test main if the `FIO_EXE` env variable is not set. Adding fio to the CI environment will be addressed as a separate PR.
