    Per-source separation of static resources & discovery

    Previously, the amalgamation of static resources and discovery
    extensions defined for all matching pipeline sources were passed
    to each pollster on each polling cycle.

    This led to unintended duplication of the samples emitted when
    an individual pollster matched several sources.

    Now, we relate the static resources and discovery extensions to
    the originating sources and only pass these when a pollster is
    traversed in the context of that source.

    Similarly, sinks are now related to the originating source and
    samples are only published over the sinks corresponding to the
    current sources.
