Staticweb shortcut object 404s

Right now static web checks to see if it should handle a
request and if it decides that it shouldn't, in all cases,
it lets the request pass through the pipeline normally.
After this change on "x-web-mode: t" obj requests where
staticweb is not setup and an object 404s it will just
return the 404 instead of letting the app send a duplicate
request to the object servers.

Add delay in swift-bench

With enable write affinity, it's necessary to wait until
replication has moved things to their proper homes before
running delete request. With write affinity turned on, only
nodes in local region will get the object right after PUT request.

Fix range GET w/If-None-Match.

An object GET request with both If-None-Match: <Etag> and
Range: bytes=N-M should result in a 304 Not Modified if the Etag
matches. However, it was resulting in a 416 Requested Range Not
Satisfiable. This commit fixes that.

The fix was to remove conditional_response=True from a request in the
proxy. As far as I can see, the only effect that
conditional_response=True has in swob is to enable range
checking. Since the object server handles all the range stuff, the
proxy shouldn't do it. Otherwise, you wind up with double-application
of the Range header, and that doesn't work very well.

This is probably left over from the WebOb days.

Fixes bug #1196805.

Don't append %interface with ipv6 ips.

- Since netifaces is appending a %interface (i.e: %eth0) at the end and
  does not make a correct ipv6 address we are removing it.
- Improve the tests of whataremyips along the way.

Removed monkeypatching of __del__ in tests

On PyPy adding __del__ to a class after it's constructed does not
work, instead implement the leakchecker in tests by using weakrefs,
which works everywhere.

Sped up tests by using smaller files

Switched one of the disk file tests to use a smaller file size for
testing. The larger size was not needed and accounted for ~3% of the
total test time by itself.

Fix unbalanced rings after initial creation.

Sometimes you'd make a ring that should have a good balance (~= 1),
but it would come out with a poor balance (>= 90). Rebalancing a
couple times would fix it, but it shouldn't be necessary to do that.

This was due to a bug in the ring builder's rebalance() method where,
when placing a replica for a partition, it would pick *one of* the
tiers with the lowest number of replicas, but the choice was made
without regard to parts_wanted.  Now rebalancing pays attention to the
drives' parts_wanted attributes, so the tier with the emptiest drive
gets the replica.

(Also fixed a typo in a completely unrelated comment.)

Migrate to pbr for build

pbr is the libification of what was openstack.common.setup. If provides
the build information in a delcarative form, instead of as executable python
code, which works around the chicken and egg problem of needing setup
libraries present to run setup, but needing to run setup to tell if you
need setup libraries.

One of the features that comes along with this is versioning based on
git tags. If the current revision is a signed git tag, then that is the
version of the package. If it is not, the version is equal to the most
recent git tag, plus a commit count, plus a git sha (similar to git
describe, but scrubbed for python version rules compliance)

pbr updates are also part of the upcoming automation around ensuring
global requirements stay in sync.

[tempauth] update token if its value changes or expires

In current codes, tempauth token will be updated only when it expires. In
token's lifetime, any changes in tempauth config file doesn't update token,
which means if you update your config file and restart proxy server, the
role in runtime might not change. So a good fix is updating token when
it changes or expires.

clean temp dir in /tmp

In unit tests, many test class use tempfile.mkdtemp in SetUp and
shutil.rmtree in tearDown.

A common wrong case is putting test data in `testdir = os.join(mkdtemp() +
'some_class')` and `rmmtree(testdir)`. As a result, /tmp/xxx/some_class
was deleted, but /tmp/xxx is still leaved in system. So a proper fix is
`rmtree(os.path.dirname(testdir), ignore_errors=1)`
