The RelatedChange introduced a _make_internal_client() method with an
unused argument 'is_legacy_conf'. This patch completes the original
intention i.e. for the selection of internal client config path to
also be moved to the new method and use the 'is_legacy_conf' arg.

If the nodepool provider uses NAT'd floating IPs, the public IP won't
actually be available locally for binding. This has caused a bunch of
failures on raxflex lately.

The account quota middleware was missing tests for the new quota count
API and it was also only testing the legacy API for quota bytes.
This adds the new APIs quota bytes and quota count to the functional
tests.

We don't need to go counting slashes or catching IndexErrors;
we've already done all the path-parsing we need to do.
This also makes it clear that stat_type can never be None.

Account quota metadata such as quota_bytes and quota_count are stored in
the `meta` namespace which users have access to. However, this should be
only available to reseller admins.
This patch adds support for writing the quota metadata to `sysmeta`
namespace, so that it is not accessible by users. The account policy
quota is already using `sysmeta` and has the namespace
`X-Account-Quota-*`, so we are following this pattern.
If present, `X-Account-Quota-Bytes` is always preferred. However, in
order to maintain backwards compatibility, `X-Account-Meta-Quota-Bytes`
will still be honoured if it exists and `X-Account-Quota-Bytes` is not
present.
This also adds some new "legacy" tests to validate backwards
compatibility.

Previously, this would reduce the account's quota to zero, which seems
like the opposite of what the operator intended.
Now, remove the quota, similar to sending an empty quota header.

- SHA256 mismatches should trip XAmzContentSHA256Mismatch errors,
 not BadDigest. This should include ClientComputedContentSHA256 and
 S3ComputedContentSHA256 elements.
- BadDigest responses should include ExpectedDigest elements.
- Fix a typo in InvalidDigest error message.
- Requests with a v4 authorization header require a sha256 header,
 rejecting with InvalidRequest on failure (and pretty darn early!).
- Requests with a v4 authorization header perform a
 looks-like-a-valid-sha256 check, rejecting with InvalidArgument
 on failure.
- Invalid SHA256 should take precedence over invalid MD5.
- v2-signed requests can still raise XAmzContentSHA256Mismatch errors
 (though they *don't* do the looks-like-a-valid-sha256 check).
- If provided, SHA256 should be used in calculating canonical request
 for v4 pre-signed URLs.

My home server has more strict controls on /tmp as it run selinux etc.
When running unittests and the default log_filename_prefix deep under
/tmp gets permission denied. It would be better to override this setting
in the tests with a good known tmp location

Previously, when handling an object POST, if the proxy got a 202 and
two connection timeouts from the 3 primary backend object servers, it
then went to two handoffs which return 404. The proxy would consider
this to be a quorum of 404s and return the client a 404 response. This
is alarming for the client.
With this patch, the proxy will only treat a 404 response from a
handoff as authoritative if it has an x-backend-timestamp header
(i.e. there's a tombstone on the handoff). POST responses never have
an x-backend-timestamp header so in the scenario described above the
proxy will return a 503.
The Related-Change previously made a similar fix such that 404s from
handoffs are already non-authoritative for object GETs and HEADs
unless they have an x-backend-timestamp header.

Sharding involves both container DB state transitions and ShardRange
state transitions. To avoid confusion, always use db_state as the var
name when referring to the container DB state value.

Some unit tests for the proxy object GET and HEAD path were setup with
insufficient mock responses. The mock connection would raise
StopIteration exceptions once the mock responses were exhausted, which
the object controller would handle as if they were error responses,
potentially distorting the test scenario.
This patch makes the set_http_connect context manager check for
unexpected requests and raise an AssertionError if any are found.

Running unittests on my home server, even though is a beast, would be
painfully slow. Running them on my laptop ran much faster. I tried
everything and couldn't figure it out.
Chris, co-author, dug in and after we ran out of options he fired up his
packet capture and realised most tests were issuing DNS queries for
`host.`. On my home server, it runs ipv6 dual stack, so these calls
would need to timeout before a test can continue.
On finding this `host.` Ben, another co-author, dug into the code and
found the only reference we have to `host` is in FakeStatsdClient.
Sure enough as I dug a little further it turns out our FakeStatsdClient
used to override a StatsdClient function `_determine_sock_family(self,
host, port)` to stop actually creating a real socket.
However, at some point the StatsdClient was refactored and that method
was renamed and changed. Which leads to a DNS lookup every time we
create a debug_logger as it brings up the socket.
As you can imagine, this happens alot!
This patch overrides the new function that handles to socket creation
`_set_sock_family_and_target(self, host, port)`. Which eliminates the
DNS call all together.

Some tests in test_account_quotas.py registered a response with
FakeSwift during setUp and then subsequently mutated the response's
headers dict. Worse, some tests then mutate the headers again and
re-use the same response.
This relies on the FakeSwift implementation not copying the original
headers when the response is registered, which may not remain the case
(as the author discovered with the Related-Change). It's also an
unnecessary shortcut.

Four new metrics have been added into task iteration process:
 'tasks.parse_errors': count of errors when parsing the task object
 'tasks.skipped': count of task objects skipped because it doesn't
 belong to this expirer.
 'tasks.delayed': count of objects is still within the delay
 'tasks.assigned': count of assigned objects to this expirer
