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).

OSDMap: reset osd_primary_affinity shared_ptr when deepish_copy_from

Base on current logic, OSDMonitor may call create_pending and
encode_pending twice for the some epoch.

In encode_pending:

tmp.deepish_copy_from(osdmap);
tmp.apply_incremental(pending_inc);

This Op would change the tmp osd_primary_affinity, but the osd_primary_affinity
is declared as ceph::shared_ptr, so this would change the osdmap too. When this
round encode_pending is proposed fail. We may call encode_pending again, but the
osdmap is changed last round, so the pending_inc would be wrong.
