Changes to the time range parameters in requests

Time range parameters from, to and timezone are deprecated in all request endpoints. Requests should include from_timestamp and to_timestamp parameters with UTC timestamps instead except endpoints for daily data like Daily Statistics. Daily Statistics requests must include date parameters from_date and to_date which will refer to user’s local date.
