mgr/volumes: Validate mon_allow_pool_delete before volume deletion

Volume deletion wasn't validating mon_allow_pool_delete config
before destroying volume metadata. Hence when mon_allow_pool_delete
is set to false, it was deleting metadata but failed to delete pool

mgr/volumes: Fix pool removal on volume deletion

While volume deletion, the associated pools are not always
removed. The pools are removed only if the volume is created
using mgr plugin and not if created with custom osd pools.
This is because mgr plugin generates pool names with specific
pattern. Both create and delete volume relies on it. This
patch fixes the issue by identifying the pools of the volume
without relying on the pattern.

rgw: cls_bucket_list_(un)ordered should clear results collection

Each call to cls_bucket_list_(un)ordered should have an empty
collection to populate with results. Rather than rely on the caller to
insure this, it's more reliable to have these functions do the clear.

Additionally in some cases, a reserve call was added to the collection
to pre-allocate the space needed for the expected number of
results. This will potentially result in fewer re-allocations plus
copies.

client: introduce timeout for client shutdown

Client::shutdown() could indefinitely wait when tearing down
MDS sessions if an MDS is unreachable during shutdown, but a
valid session existed, i.e., Client::mount() was successfull.

These failures were initially observed in mgr/volumes tests in
teuthology and lately during rados/mgr selftests where manager
plugins do not respawn as volumes plugin waits for cleaning up
libcephfs handles via Client::shutdown().
