extra_hardware plugin should optionally convert data from edeploy format

[Dmitry Tantsur]

eDeploy's python-hardware collects a lot of information, but does it in a bit unusual format: list of lists. To be able to use it with introspection rules we need to convert it to dicts.

    Convert eDeploy data so that rules can process it

    eDeploy's return format is a list of lists, in order to use it with
    introspection rules we must convert it to dictionary format. This patch
    detects if the data is in eDeploy's format and will convert it storing
    the new data in introspection_data['extra']. introspection_data['data']
    is assumed unusable by introspection rules and will always be removed
    from introspection_data after the data is stored in swift.
