Allow for specifying arbitrary date/time range in Analytics along with granularity / grouping period

Customer would like to be able to filter analytics data with more granularity than is available through the UI, currently the API is not exposed so customer is stuck with the time ranges (minimum of 15 mins) and grouping period / granularity (currently seems to be 1 min only for the 15 min range, or just counts of SUCCESS and FAILURES in longer periods)

Furthermore, the only options for customizing date ranges (absolute) for reports is by day. It would be helpful to be able to filter by time of day to be able to isolate time windows for issues or test results. A particular use case is to zoom in around a precise time to further investigate issues.
