Run RadosModel-based integration tests.

clients: [client list]
ops: <number of ops>
objects: <number of objects to use>
max_in_flight: <max number of operations in flight>
object_size: <size of objects in bytes>

max_stride_size: <maximum write stride size in bytes>
op_weights: <dictionary mapping operation type to integer weight>

tasks:

clients: [client.0]
ops: 1000
