Extend device_devices table (#1471)
* Add last_used_ts and IP to database

* Add migrations

* Rename column
Prepare statements

* Add interface method and implement it

Signed-off-by: Till Faelligen <tfaelligen@gmail.com>

* Rename struct fields

* Add user_agent to database

* Add userAgent to registration calls

* Add missing "IF NOT EXISTS"

* use txn writer

* Add UserAgent to Device
