Implement UOWS client in autoreduction

[MarcusNoble]

Create a client to communicate with the User Office webservice to be used by the custom authentication for verifying SessionIDs and getting basic user information to populate the User table with.

Could make use of ​https://bitbucket.org/jurko/suds for the SOAP communication as it is already being used by the ICAT client.

Will need to handle ws.checkSession(), ws.getPersonDetails() and logout().

For Tester:

1. Connect to datareducedev.isis.cclrc.ac.uk
2. sudo su
3. export PATH="/usr/local/bin:$PATH"
4. cd /var/www/autoreduce_webapp
5. python manage.py test autoreduce_webapp.tests.UOWSClientTestCase
6. When asked for credentials enter your user office system credentials (​https://devusers.facilities.rl.ac.uk/auth/)

Expected outcome:

[root@datareducedev autoreduce_webapp]# python /var/www/autoreduce_webapp/manage.py test  autoreduce_webapp.tests.UOWSClientTestCase

These tests require that you have a user account on the dev user office system. https://devusers.facilities.rl.ac.uk/auth/
UserOffice WebService Username: marcus.noble@stfc.ac.uk
