Peter Portante 067b41e854 In-process swift server for functional tests
Provide a way to run the functional tests using a p/a/c/o server setup
in the same process running the nosetests infrastructure.

By setting the environment variable, SWIFT_TEST_IN_PROCESS, to a true
value, the functional test framework will construct a set of proxy,
account, container and object servers running in the same process that
is running the functional tests, ignoring any external swift
service. This in-process swift environment is akin to the one used in
test/unit/proxy/test_server.py.

Setting that same environment variable to a false value will ensure the
in-process servers are not used.

When the above environment variable is not present, and the
/etc/swift/test.conf is _not_ present (or present but empty) on the
system where the functional tests are executing, the in-process
environment will be used. Previously, if no /etc/swift/test.conf file
was found, the tests would just be marked as skipped.

Using this in-process method allows one to gather code coverage using
the functional tests to exercise code paths, in addition to the unit
tests, or more easily debug existing functional tests, or even write new
ones.

There are two constraints that are changed for use with the in-process
functional tests: max_file_size is lowered to roughly 8 MB, and
client_timeout is set to 4s.
