boto: EC2 instance get_attribute results in AttributeError: 'EC2Connection' object has no attribute 'describe_attribute'
Question: **What steps will reproduce the problem?**

1.attempt to get a running EBS-backed instance's kernel attribute with
instance.get_attribute('kernel')

    
    
    >>> import boto.ec2
    >>> regions = boto.ec2.regions()
    >>> regions
    [RegionInfo:eu-west-1, RegionInfo:us-east-1, RegionInfo:us-west-1, RegionInfo:ap-southeast-1]
    >>> usw = regions[2]
    >>> conn = usw.connect()
    >>> reservations = conn.get_all_instances()
    >>> reservations
    [Reservation:r-XXXXXXXX]
    >>> r1 = reservations[0]
    >>> for i in r1.instances: print i
    ...
    Instance:i-XXXXXXXX
    >>> instance = r1.instances[0]
    >>> instance.get_attribute('kernel')
    Traceback (most recent call last):
      File "<stdin>", line 1, in <module>
      File "/Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/site-packages/boto/ec2/instance.py", line 293, in get_attribute
        return self.connection.describe_attribute(self.id, attribute)
    AttributeError: 'EC2Connection' object has no attribute 'describe_attribute'
    >>> 
    

**What is the expected output? What do you see instead?**

expect to get the attribute, but instead get this error: AttributeError:
'EC2Connection' object has no attribute 'describe_attribute'

**What version of the product are you using? On what operating system?**

boto.Version == 2.0b3 on Mac OS X 10.5 (boto installed using pip)

**Please provide any additional information below.**

Code on github repo seems to also indicate that there's not a
describe_attribute

Answer: Problem was promptly fixed by the developers!

<https://github.com/boto/boto/commit/899ab55752d31af22f41168f92fe39553504d6fc>

However at time of writing, it's still not on pypi (so pip install --upgrade)
won't help - must git clone and install from there.
