This patch adds a SwiftService class that incorporates the high
level logic from swiftclient/shell.py. It also ports shell.py to
use the new class, and updates the code in swiftclient/multithreading.py
to allow the SwiftService to be used for multiple operations whilst
using only one thread pool.
Currently, code that imports swiftclient has to have its own logic for
things like creating large objects, parallel uploads, and parallel
downloads. This patch adds a SwiftService class that makes that
functionality available in Python code as well as through the shell.

Implements: blueprint bin-swift-logic-as-importable-library
This patch extracts the multi-threading code from bin/swift into
swiftclient/multithreading and adds tests. In particular, this new way
of doing it (with context managers) will prevent non-daemonic threads
from wedging the process when unexpected exceptions happen.
I enabled reporting of which lines, specifically, are not covered by
unit tests (added -m option to "coverage report" in .unittests).
This patch includes a drive-by fix for uploading a segmented file with
--use-slo when that object already exists. A key of "name" was used
instead of "path", raising KeyError.
There's also another drive-by fix for uploading segmented objects with
--use-slo. Commit 874e0e4427b80e1b15b74a1557b73ba9d61443ca regressed
this by removing the capturing of thread-worker results in
QueueFunctionThread.run(). This patch restores that functionality and
the feature (uploading SLO objects).
