[trace view] Different color for spans from different instances of the same service

Requirement - what kind of business use case are you trying to solve?

Easy interpretation of larger applications with multiple internal spans from different components.

Problem

Spans from the same service all have the same color, making it hard to easily and visually separate which component inside the service the span is related to.

Proposal

Extend the existing color generator to also allow different coloring of spans with different values in the component tag.

Perhaps a two color scheme would make sense where the line (edge of the rectangle) would have the service color, and then you would have a component color as the fill.

    /**
     * COMPONENT is a low-cardinality identifier of the module, library, or package that is instrumented.
     */
    public static final StringTag COMPONENT = new StringTag("component");

Any open questions to address
