* Update docs/submodules/functest from branch 'master'
  - Merge "Add UEFI support in functest"
  - Add UEFI support in functest

    Add extra properties to the cirros image
    for ARM architecture.
    In the glanceclient repository, the create method
    expects **kwargs as parameters, thus an extra_properties
    variable containing a dictionary of property-value pairs
    can be added (if given) to the image to be created.
    If the properties do not appear, the call should not affect
    the image properties because the dictionary is initialized
    as empty.
