feat(functions): Include examples in functions trends timeseries

[Zylphrex]

A simple list of examples isn't very meaningful in this context. We want a list of examples that can be associated with a timestamp. This adds a timeseries that includes up to 1 example profile per bucket in the roll up so that we can pick out examples at various points in time.
