@edigaryev
Get a fresh instance of executor for each benchmark invocation
17cc5c6 
And don't pre-initialize all of the executors at once, as this
might reach the maximum number of VMs limit in case we want to
test multiple Tart executors.
@edigaryev
Run benchmarks on Tart with different --root-disk-opts options
df0ccb9
@edigaryev
Fix TestTart
31e2609
@edigaryev
benchmark fio: introduce --prepare command-line argument
51a1687 
To be able to specify --prepare='sudo purge && sync', similarly to
Hyperfine[1].

@edigaryev
Remove random writing tests to make space for more read/read-write tests
b40cbc8
@edigaryev
Add some "randrw"-style fio benchmarks
