max virtio slots value for instances aren't maintained on resize

[Matt Rabe]

The DefaultStandardize object in pypowervm defaults the max virtio slots value to 64. nova-powervm always creates the DefaultStandardize object with this default which means that on every resize operation nova-powervm will always attempt to set the value to be 64.

    Persist existing LPAR wrapper attributes in DefaultStandardize on resize

    The DefaultStandardize object in pypowervm defaults the proc units
    factor, max virtio slots, uncapped weight, spp, availability
    priority, srr, proc compat, and lpar metric values. nova-powervm
    does not pass in these parameters when resizing.

    This results in these attributes being set to the default defined
    by the DefaultStandardize object for every resize operation. This
    change passes those parameters into the DefaultStandardize object.

    Note that if the attributes were passed in as part of the flavor
    then the flavor's values would be set later in the DefaultStandardize
    object by the LPARBuilder.

    Persist existing LPAR wrapper attributes in DefaultStandardize on resize

    The DefaultStandardize object in pypowervm defaults the proc units
    factor, max virtio slots, uncapped weight, spp, availability
    priority, srr, and proc compat (note that the enable lpar metric
    parameter isn't included in this stable/pike commit as the minimum
    pypowervm requirement for Pike does not support that parameter).
    nova-powervm does not pass in these parameters when resizing.

    This results in these attributes being set to the default defined
    by the DefaultStandardize object for every resize operation. This
    change passes those parameters into the DefaultStandardize object.
