core config variable CLOUDSDK_SCOPES is tuple, should be list, breaks method _CheckForExtraScopes()

[GoogleCodeExporter]

What steps will reproduce the problem?
=========================
in a bash terminal:
export CLOUDSDK_EXTRA_SCOPES=any_value
gcloud -h

If CLOUDSDK_EXTRA_SCOPES is set to any value, any commands to gcloud will be 
broken.

What is the expected output? What do you see instead?
==================================
Expect to see a list of commands allowed to follow 'gcloud' when executing 
'gcloud -h'.  Instead I get a traceback:

What is the output of 'gcloud info'?

==============================
Everything worked fine after I edited 
/Users/me/google-cloud-sdk/./lib/googlecloudsdk/core/config.py so that global 
variable CLOUDSDK_SCOPES was a list (for which the 'extend' method is defined) 
rather than a tuple (which has no method 'extend').  This variable is defined 
on lines 276-282.

This will break shit for anyone trying to use the datastore, and it's a very, 
very, very quick fix.  I think you should prioritize this higher.

This was somewhat undocumented feature. In a process of removing something 
else, a bug was made where list got changed to tuple.

Note that latest version no longer supports CLOUDSDK_SCOPES environment 
variable.

> will break shit for anyone trying to use the datastore

you no longer need to set CLOUDSDK_EXTRA_SCOPES for datastore.
