isoblue-software_1.6.9

Improvements for this release:

• More aggressive scheme for re-establishing cell connectivity
• GPS logging better handles suspend + wake cycle
• Graceful shutdown/wake of Kafka and all logging services during the suspend + wake cycle

isoblue-software_1.6.8

Fix: suspend using systemctl

isoblue-software_1.6.7: Remove: sphagetti code for reconnecting cell

The previous method for reconnecting cellular is kinda hacky. Couple of things
we tried:
* udevadm trigger (kinda mysterious)
* put in get-pgns systemd (problem is that dhclient will die after systemd
service exits)

Now we have a separate scripts and a systemd service for:
* re-register the modem onto the network using qmicli
* dhclient wwan0

The systemd service is set to `RemainAfterExit=yes` so dhclient will remain
running.

isoblue-software_1.6.6: Add: a delay after running dhclient

We don't want get-pgns service to restart right after dhclient just got run.

isoblue-software_1.6.5

Add: better way to restart cell network

isoblue-software_1.6.2: Remove: net-strength.service dependency

net-strength.service was merged into heartbeat.service
