Christian Schwede 47546eb145 Show warning when auth_version >= 2 and keystoneclient is missing
Swiftclient hangs forever without any reasonable hint if someone
uses a recent version of swiftclient together with auth version
2 or later. The reason for this is the sys.exit() call in a thread
- the main thread never exists, and swift just waits forever.

Raising a ClientException instead of calling sys.exit() fixes this
and returns the desired information back to the user.
