Decimal imported but not used in ubuntu-sso-login

[Manuel de la Peña]

After the merge of https://code.launchpad.net/~ballogy/ubuntu-sso-client/drop-lazr/+merge/107153 lazr is not longer a dependency and accoding to the comments in the code:

# import decimal even if we don't need it, pylint: disable=W0611
import decimal
# This is a workaround for LP: #467397. Some module in our depency chain sets
# the locale and imports decimal, and that generates the following trace:
# Traceback (most recent call last):
# File "/usr/lib/ubuntu-sso-client/ubuntu-sso-login", line 33
# from ubuntu_sso.main import SSOLogin
# File "/usr/lib/pymodules/python2.6/ubuntu_sso/main.py", line 42
# from lazr.restfulclient.resource import ServiceRoot

# from decimal import Decimal
# File "/usr/lib/python2.6/decimal.py", line 3649, in <module>
# val = globals()[globalname]
# KeyError: 'ROUND_CEiLiNG'

decimal does not longer need to be imported.
