If we are creating the kernel forwarding table, we have to make sure it
has been deleted already, otherwise we can get into collisions with the
already setup forwardings, and the subsequent add will fail anyway.

Even though this is a false-positive, it confuses checkbashisms. So
let's rename the variables to something else, even more descriptive,
to avoid the check error.

We want to have the same behavior as within
ngcp-rtpengine-recording-daemon's init script.  Let's avoid code
duplication between start/stop vs restart and instead invoke
plain stop + start actions via restart.

While at it fix missing 'set -e' that was caught by Richard
during creation of ngcp-rtpengine-recording-daemon's init
script.

The redis onekey concepts is introduced to reduce traffic to redis
and redis notification traffic.
It modifies the current structure for one call in redis, which are
multiple keys with pre- and postfixes and the callid in between to
one key with the structure "json-<callid>". The value is a json
formatted string with the previous multi-key identifiers in it.
