I just completed a fresh install of 17.04 today, and it appears that you are correct, TLP is no longer included.
I saw no reason to install TLP at this point, so I disabled the Bluetooth service by running the following command in the terminal.
sudo systemctl disable bluetooth
This will survive a reboot, and the blueman applet did not load on startup.
To check if Bluetooth is enabled run
systemctl is-enabled bluetooth
To enable Bluetooth again run
sudo systemctl enable bluetooth
After disabling Bluetooth as shown above, the service turns off on the next reboot, or on the next stop event. The same goes for enabling Bluetooth again.
To manually stop Bluetooth run
systemctl stop bluetooth
EDIT May 15, 2017
The above method does not work on Ubuntu Mate 16.04 unless you also disable TLP.
sudo systemctl disable tlp
However if your using a laptop you may not want to do this due to power saving considerations.
