Julia Kreger 6f1c603b5b CI: Enable the ability to have test VMs with different block sizes
Recently we became aware that some operators might need a larger
block size, but our CI testing doesn't represent any ability to
assert a different block size.

We can now assert a block size override in the scripting which
allows us to create a CI job.
