TempURL: Fixed bug with \r or \n in disposition.

If an object had a \r or \n in its name, it would end up creating an
invalid HTTP Content-Disposition header. Reviewer consensus was to use
URL encoding.

Fix coverage report for newer versions of coverage

With newer versions of coverage (at least what is installed with ubuntu
trusty), code coverage isn't working.  Making this change allows the
coverage library to find the swift package.

Plumb insecure flag to functests

The problem arises when running functests against pre-existing
clusters configured with self-signed certificates. As far as
security goes, doing that is rather useless, but it happens.
Such testing worked previously, but with the switch to Requests
in the client, we must plumb "insecure" flag. There's no other
way to do it in Requests, no environment variable, anything.

Add --quoted option to swift-temp-url

If you have a path with special characters it may be easier to hand them to
swift-temp-url prequoted than try to escape them on the command line.  By the
time common.middleware.tempurl gets ahold of the path it's unquoted so we do
the same before calculating the hmac but still use the pre-quoted path output
to the commandline.

Add profiling middleware in Swift

The profile middleware provide a tool to profile Swift
code on the fly and collect statistic data for performance
analysis. An native simple Web UI is also provided to help
query and visualize the data.

Print pipeline names in the reported pipeline

When current code modifies the pipeline, it prints the entry point
names instead of the names used to construct the pipeline. This is
inconvenient because a sysadmin cannot copy and paste from the log.

We already save the pipeline name into contexts in most cases, so
the fix simply reuses that to provide friendly names.

Uses None instead of mutables for function param defaults

As seen on #1174809, changes use of mutable types as default
arguments and defaults them within the method. Otherwise, those
defaults can be unexpectedly persisted with the function between
invocations and erupt into mass hysteria on the streets.

There was indeed a test (TestSimpleClient.test_get_with_retries)
that was erroneously relying on this behavior. Since previous tests
had populated their own instantiations with a token, this test only
passed because the modified headers dict from previous tests was
being overridden. As expected, with the mutable defaults fix in
SimpleClient, this test begain to fail since it never specified any
token, yet it has always passed anyway. This change also now provides
the expected token.

debug level logs should not be translated

https://wiki.openstack.org/wiki/LoggingStandards debug messages
should not be translated. Like mentioned in several changes in
Nova by garyk this is to help prioritize log translation.

Let users add their own txid suffixes

The value of the X-Trans-Id-Extra header on the request (if any) will
now be appended to the transaction ID. This lets users put their own
information into transaction IDs.

For example, Glance folks upload images as large objects, so they'd
like to be able to tie together all the segment PUTs and the manifest
PUT with some operation ID in the logs. This would let them pass in
that operation ID as X-Trans-Id-Extra, and then when things went
wrong, it'd be much easier to find all the requests in Swift's logs.

Also, this aids debuggability when requests fail to receive
responses. If a user is sending in their own X-Trans-Id-Extra strings,
then that gives operators something to search for in the logs. The
normal txid won't work since that's in the response, but the client
didn't receive one.

Swift will only use the first 32 characters of X-Trans-Id-Extra so
that its log lines stay a manageable length. Also, it's URL-quoted so
that users cannot inject double quotes into X-Trans-Id-Extra and screw
up log parsers.

Add targeted config loading to swift-init

This allows an easier and more explicit way to tell swift-init to run on
specific servers.  For example with an SAIO, this allows you to do
something like:

swift-init object-server.1 reload

to reload just the 1st object server.  A more real world example is when
you are running separate servers for replication.  In this example you
might have an object-server/public.conf and
object-server/replication.conf.  With this change you can do something
like:

swift-init object-server.replication reload

to just reload the replication server.
