Integrate fio & bdevio with SPDK backend and RBD/LSVD as part of GitHub actions

[knikolla]

Outgrowth of #30

[knikolla]

Made progress getting bdevio tests to run on a RBD (non LSVD backend)

Starting bdevio with the -w flag starts SPDK and awaits RPC calls to configure the bdev and perform tests.
