feat(tazjin/tverskoy): Configure tlp to keep battery between 40-70%

Browse source 
This is supposedly better for battery health, and since the machine is
usually plugged in while in the office it might be a good idea.

Note for myself: `sudo tlp fullcharge` ~30 min before needing to leave
with a fully charged battery.
