Title: #issue-421 supporting kt ucloud storage driver

kt ucloud storage is based on swift.
but kt customized it.
so default cloudfiles driver doesn't work for it.

so I patched 2 thigns.
1. using auth_uri variable to change auth url address.
for example:
currently cloudfiles driver's auth entry point is fixed. so we can't change it.
to set auth_uri, now we can change it.

2. add ktucloud storage driver.
It is inherited cloudfiles.py and set some parameters.
so it is very easy to read.
