CLIMATE-402 - Fix ParameterSelectCtrl time value initialization

- The default start time is now set to 1900-01-01. This should prevent
  the dataset's start time from being prior to this date and thus
  ignored.
CLIMATE-403 - Integrate /parameters/bounds endpoint into UI

- Add getObservationBounds for retrieving bounds information from RCMED.
  This grabs all the parameter information from RCMED and stores it in
  observationBounds.
- Add getBoundsByParameterId helper for retrieving parameter information
  when adding a dataset. If not information is present for the requested
  parameter Id then a default value is returned instead.
