Automate functional tests

By storing the functional tests configuration files in the
repo, we can now run the functional_tests.sh to setup,
run the functional tests, and teardown.

Most likely this will be able to be run as a user from
the same directory as the repo, but at the moment, the
configuration files are copied to /etc/swift.

The only requirements are:
1. /etc/swift does not exist.  That way the tests will
not interfere with an existing deployment.
2. /mnt/gluster-object/test and /mnt/gluster-object/test2
must have been created and setup correctly on an XFS
or GlusterFS volume
3. sudo rights without password prompt
4. glusterfs-openstack-swift-* rpm must not be installed
on the system

Once the requirements are met, you can execute the tests
as follows:

$ bash tools/functional_tests.sh
