    Require Port Pairs to share same correlation type

    When creating Port Pair Groups, validation of each Port Pair's
    correlation type will now occur.
    Every Port Pair needs to share the same correlation type
    when they get attached to a specific Port Pair Group.
    This guarantees homogeneity in the composition of a Port Pair Group
    and clarifies the definition and feature set of each hop of a chain.

    Creating and Updating Port Pair Groups now verifies whether all PPs are
    consistent with regards to the correlation type selected.

    The workaround to achieve "homogeneous" next-hops in the OVS driver
    introduced by Iebdfca5467ca33cfd9d93d55f47d6b57b79dffbe
    has been removed, so were a couple of related tests.

    Documentation has been updated.
