Replace the systemd unit files that needed to be modified for a
specific interface with template files. The template files allows one
to instansiate a service for any interface (by running systemctl
start pping@<interface>.service), and multiple interfaces can be
monitored at once.
Each instance maintains a separtate "log" of data at
/sys/var/log/pping/<interface>/pping.<interface>.json which is rotated
one per minute (see the rotate-pping@.timer file) and placed in daily
subfolders.

In case ePPing is not shut down cleanly (ex. when killed with SIGKILL
or OOM killer) it will not be able to detach its eBPF programs, may
remain attached and waste resources. Add a script which can be used
to clean up any remaining programs tc-eBPF programs.
Note, this script should not be run while the any instace of pping is
still running, as that will remove its tc programs and thus its
ability to function properly.

Add some example files for setting up ePPing with systemd.
The setup creates "log" files in /var/log/pping and rotates
them every minute (appending a date at the time of rotation).
