    Squashed backport for 'NovaAllowResizeToSameHost' parameter
    
    We squashed the backports because the first patch wasn't right, so for
    full history we backports the 2 patches in the same time.
    
    1) Add 'NovaAllowResizeToSameHost' parameter
    
    This parameter is used quite often but is not currently exposed in THT.
    Close that gap. This is used by the API so it is that container that's
    modified.

    (cherry picked from commit 0b63621a5e40d53166fe8a5625236bed82e1b3f4)
    
    2) Fix allow_resize_to_same_host
    
    allow_resize_to_same_host is in nova::api class, not ::nova.
