Refactor server side copy as middleware

Browse Source 
Rewrite server side copy and 'object post as copy' feature as middleware to
simplify the PUT method in the object controller code. COPY is no longer
a verb implemented as public method in Proxy application.

The server side copy middleware is inserted to the left of dlo, slo and
versioned_writes middlewares in the proxy server pipeline. As a result,
dlo and slo copy_hooks are no longer required. SLO manifests are now
validated when copied so when copying a manifest to another account the
referenced segments must be readable in that account for the manifest
copy to succeed (previously this validation was not made, meaning the
manifest was copied but could be unusable if the segments were not
readable).

With this change, there should be no change in functionality or existing
behavior. This is asserted with (almost) no changes required to existing
functional tests.

Some notes (for operators):
* Middleware required to be auto-inserted before slo and dlo and
  versioned_writes
* Turning off server side copy is not configurable.
* object_post_as_copy is no longer a configurable option of proxy server
  but of this middleware. However, for smooth upgrade, config option set
  in proxy server app is also read.

"""
Server side copy is a feature that enables users/clients to COPY objects
between accounts and containers without the need to download and then
re-upload objects, thus eliminating additional bandwidth consumption and
also saving time. This may be used when renaming/moving an object which
in Swift is a (COPY + DELETE) operation.
The server side copy middleware should be inserted in the pipeline after auth
and before the quotas and large object middlewares. If it is not present in the
pipeline in the proxy-server configuration file, it will be inserted
automatically. There is no configurable option provided to turn off server
side copy.
--------
Metadata
--------
* All metadata of source object is preserved during object copy.
* One can also provide additional metadata during PUT/COPY request. This will
over-write any existing conflicting keys.
* Server side copy can also be used to change content-type of an existing
object.
-----------
Object Copy
-----------
* The destination container must exist before requesting copy of the object.
* When several replicas exist, the system copies from the most recent replica.
That is, the copy operation behaves as though the X-Newest header is in the
request.
* The request to copy an object should have no body (i.e. content-length of the
request must be zero).
There are two ways in which an object can be copied:
1. Send a PUT request to the new object (destination/target) with an additional
header named ``X-Copy-From`` specifying the source object
(in '/container/object' format). Example::
curl -i -X PUT http://<storage_url>/container1/destination_obj
-H 'X-Auth-Token: <token>'
-H 'X-Copy-From: /container2/source_obj'
-H 'Content-Length: 0'
2. Send a COPY request with an existing object in URL with an additional header
named ``Destination`` specifying the destination/target object
(in '/container/object' format). Example::
curl -i -X COPY http://<storage_url>/container2/source_obj
-H 'X-Auth-Token: <token>'
-H 'Destination: /container1/destination_obj'
-H 'Content-Length: 0'
Note that if the incoming request has some conditional headers (e.g. ``Range``,
``If-Match``), the *source* object will be evaluated for these headers (i.e. if
PUT with both ``X-Copy-From`` and ``Range``, Swift will make a partial copy to
the destination object).
-------------------------
Cross Account Object Copy
-------------------------
Objects can also be copied from one account to another account if the user
has the necessary permissions (i.e. permission to read from container
in source account and permission to write to container in destination account).
Similar to examples mentioned above, there are two ways to copy objects across
accounts:
1. Like the example above, send PUT request to copy object but with an
additional header named ``X-Copy-From-Account`` specifying the source
account. Example::
curl -i -X PUT http://<host>:<port>/v1/AUTH_test1/container/destination_obj
-H 'X-Auth-Token: <token>'
-H 'X-Copy-From: /container/source_obj'
-H 'X-Copy-From-Account: AUTH_test2'
-H 'Content-Length: 0'
2. Like the previous example, send a COPY request but with an additional header
named ``Destination-Account`` specifying the name of destination account.
Example::
curl -i -X COPY http://<host>:<port>/v1/AUTH_test2/container/source_obj
-H 'X-Auth-Token: <token>'
-H 'Destination: /container/destination_obj'
-H 'Destination-Account: AUTH_test1'
-H 'Content-Length: 0'
-------------------
Large Object Copy
-------------------
The best option to copy a large option is to copy segments individually.
To copy the manifest object of a large object, add the query parameter to
the copy request::
?multipart-manifest=get
If a request is sent without the query parameter, an attempt will be made to
copy the whole object but will fail if the object size is
greater than 5GB.
-------------------
Object Post as Copy
-------------------
Historically, this has been a feature (and a configurable option with default
set to True) in proxy server configuration. This has been moved to server side
copy middleware.
When ``object_post_as_copy`` is set to ``true`` (default value), an incoming
POST request is morphed into a COPY request where source and destination
objects are same.
This feature was necessary because of a previous behavior where POSTS would
update the metadata on the object but not on the container. As a result,
features like container sync would not work correctly. This is no longer the
case and the plan is to deprecate this option. It is being kept now for
backwards compatibility. At first chance, set ``object_post_as_copy`` to
``false``.
