Implement set and get bluetooth of devices.

[JeannedArk]

This contributes to the server side, see this ticket:
openstf/STFService.apk#18
and the corresponding pull request:
openstf/STFService.apk#20

The STFService.apk was updated to the changes in the pull request in order to be able to set and get the Bluetooth status. The .proto files have been adjusted. The functionality was very similiar implemented to the WiFi functionality. Like for WiFi, similiar buttons have been added to the Device->Automation view.

Be aware, that setting and getting the Bluetooth status is only possible with the new updated .apk, otherwise a timeout occurs.

Those lines should be after line 82 with ConnectStoppedMessage.

Rebased and fixed that issue

Tooltips still refer to WiFi

I tested this on a Huawei Mate 10 just now. It does work, however there's a bug. When bluetooth is disabled, and you use the STF UI to enable it, bluetooth gets enabled just fine. However, after a few seconds the STF UI shows that bluetooth is disabled. So, in other words, when you click on the "enable" button, it works and looks fine for a brief moment ("enable" button is blue). But then the "enable" button deactivates and the "disable" button becomes blue. If I go to another tab in STF and then back to the "Automation" tab, it shows correctly again ("enable" is blue). Maybe some sort of a timing issue?

By the way on the Mate 10 there's a dialog that pops up on the device every time you enable Bluetooth. It says "STFService is trying to turn on Bluetooth. Allow?" Might be related and/or causing the timing issue

I have merged openstf/STFService.apk#20 now. I believe that the bug I mentioned is related to the changes here. Note that you'll also have to bump the STFService version as follows:
