Bug description:
  [Impact]

  Example when using a key name 'my key':

  Caught exception reading instance data:
  http://169.254.169.254/2009-04-04/meta-data/mpi/my key

  Is a boto issue, see https://github.com/boto/boto/issues/659

  Patches provided for Precise, Quantal and Raring. Fix already exists
  in Saucy.

  [Test Case]

  There are two ways to test this. The first provides that the change will affect
  the url in the required manner but does not test the package. The second will
  test the package but needs to be run within an Openstack instance against an
  API that has calls with spaces on their name.

  ====
  #!/usr/bin/env python
  import urllib

  resource = "http://169.254.169.254/2009-04-04/meta-data/i love spaces"
  print "unsafe: %s" % resource

  resource = urllib.quote(resource, safe="/:")
  print "safe: %s" % resource

  ===
  #!/usr/bin/env python
  from boto import utils
  utils.get_instance_metadata()

  
  [Regression Potential]
   This is a very low risk change. It has been tested on Precise. A quantal patch is also provided.
