rgw: async ops can generate new stacks for parallel execution

Can now have an op generating another op that will be called at
a different stack. The current op will halt execution until new
op finishes. We can call this multiple times so that multiple ops
will be executed concurrently. This can be useful in the case we
want to generate a single op that will read from multiple objects,
after it had read some meta information. So the root op will read
the meta information and will generate multiple request that will
execute concurrently (albeit on a single thread).
