ReplicatedPG: copy: conditionally requeue copy ops when cancelled

We may need to requeue copy ops which are cancelled as part of an acting
set change but don't change the primary. To support this, add a
"requeue" flag to cancel_copy_ops() and copy_ops(), as well as to
CopyResults. The CopyCallback is then responsible for requeuing (the
higher layers can't do so as they can't know which request actually
triggered the copy).

common: get_command_descriptions use cout instead of dout

Using dout instead of cout creates noise and makes it more difficult for
people trying to debug a failure in test_ceph_argparse.py.

The output of get_command_descriptions is modified to only contain
parseable information and the code parsing its output
test_ceph_argparse.py is removed.

client: fix invalid iterator dereference in Client::trim_caps()

trimming inode drops a reference to the inode's parent, it may cause
the inode's parent also be trimmed. If the cap iterator 'p' happens to
point to the inode's parent and the inode's parent is trimmed, the cap
iterator 'p' become invalid.

Fix the issue by delaying removing cap from the seesion cap list.
(similar to what the kclient does)

mds: update backtrace when old format inode is touched

We updated inode format version to 7 when introducing inode backtrace.
If we found a inode's format version < 7 when fetching the inode, set
the inode's backtrace_version to 0, to indicate the inode's backtrace
is out of data. When touching a inode with backtrace_version == 0, we
also update its backtrace.

rgw: turn swift COPY into PUT

Fixes: #6606
The swift COPY operation is unique in a sense that it's a write
operation that has its destination not set by the URI target, but by a
different HTTP header. This is problematic as there are some hidden
assumptions in the code that the specified bucket/object in the URI is
the operation target. E.g., certain initialization functions, quota,
etc. Instead of creating a specialized code everywhere for this case
just turn it into a regular copy operation, that is, a PUT with
a specified copy source.

rgw: get rid of req_state.bucket_name

No need for this field, as we already have req_state.bucket_name_str.
This saves us some memory allocation / freeing through every request
processing.
