Add x-targomo-environment header for client requests

[marionmaiden]

The services which make inter service requests to core need to forward the x-targomo-environment via java client requests.

Some of the requests that needs to be changed:

• Cp3o

  • MultiGraphRequest.executeRequestGeoJson(client, travelOptions);
  • ReachabilityRequest(client, travelOptions).get();

• Statistics service

  • ReachabilityRequest(client, options).get()

• Quality Service

  • PointOfInterestRequest(client, travelOptions).getSummary()
  • PointOfInterestRequest(client, travelOptions).get()
  • TimeRequest(CLIENT, travelOptions).get()
  • StatisticsRequest(client, travelOptions).get(StatisticMethod.CHARTS_DEPENDENT)
