add analytics

[edge-marge]

do not merge - missing distinct_id

[orcist]

@edge-marge wouldn't this implementation create a new instance of AnalyticsApi every time you access the property? Maybe it would be better to declare it once as a property and reuse it after?

private AnalyticsApi Analytics = new AnalyticsApi(getDistinctId());

also, it seems this implementation has hardcoded the UTM source, could you instead get the value dynamically from EdgegapWindowMetadata.DEFAULT_UTM_SOURCE_TAG?
