Tracking service: initial prototype with fused location

[wonder-sk]

• service does not run in a separate process anymore
• using FLP to get location
• seems to track well even with screen turned off

to-do:

• make the code more robust & finish things
• test with various android versions
• maybe record track to a file anyway, to prevent data loss? (commit the recorded track on app restart)
• better android notification - regularly update tracking time and distance
• use or don't use fused provider for tracking consistently with what positionkit uses

things to fix at some point:

• after switching back to the app while tracking, the PositionKit's location may be old for a couple of seconds, and the tracking line may end with one long segment towards this outdated location, confusing the user. maybe we should update PositionKit's location from the latest tracked point
• after switching back to the app after tracking for a longer time (at least a couple of minutes), the screen may stay black for a few seconds before showing things - maybe processing delayed track points?

• Update interval -> should we keep project settings or just use a fixed one. Compare battery-efficiency on different update frequencies
• Simulate missing Google Play (in system settings) -> Huawei phones
• Use position provider that is selected in the app
• Handle situation when app is killed by swiping it out while tracking is running (it keeps tracking at the moment)
