Adding support for encrypted backups.

We'd like to enable the backups that are taken and stored as files in Swift, to
be encrypted. We'll add some new config flags, to mark whether or not
encryption is enabled. At this point, the encryption key will also be stored as
a config value. When configured to encrypt, the whole process will be streamed
to/from Swift, doing backup -> zip -> encrypt -> Swift and Swift -> decrypt ->
unzip -> restore all during streaming, so we don't use up more disk space than
needed.

Change server exceptions to show less details

Internal exceptions were dumping error messages raised by
arbitrary python calls and potentially revealing sensitive
details.

The message for all 500 errors is now::

    Internal Server Error. (<UUID>)

The original exception details are written to the log files. The
UUID can be used to reference the individual 500 error in the log.

Fix faulty 404 errors when requesting bad versions

The problem came down to the `_dispatch` method of the openstack
common wsgi router object. When a match was not found it returned
a webob 404 exception directly rather than allowing it to be
wrapped in a serializer.

The fix involved extending the `Router` object and reimplementing
the `_dispatch()` method to use the `Fault` object that serializes
exceptions.
