Use data_update instead of rrd_update/rrd_create and influx_update
Centralize rrd file check so we can check against a remote rrdcached server too
Use rrd_name() to generate rrd file names
$this_port already gets defined within include/polling/ports.inc.php
so there's no need to redefine it again in each submodule.

In 2c9df26bbf I broke the association of
ports in the DB and ports just polled via SNMP for the adsl, etherlike
and poe submodules and no one noticed. This fixes this issue. Sorry.

By default libreNMS used the ifIndex to associate ports just found via SNMP
with ports discoverd/polled before and stored in the database. On Linux boxes
this is a problem as ifIndexes are rather likely to be unstable between reboots
or (re)configuration of tunnel interfaces (think: GRE/OpenVPN/Tinc/...), bridges,
Vlan interfaces, Bonding interfaces, etc.
This patch adds a »port association mode« configuration option per device which
allows to map discovered and known ports by their ifIndex, ifName, ifDescr, or
maybe other means in the future.
The default port association mode still is ifIndex for compatibility reasons.
As port RRD files were stored by their ifIndex before, they are now identified
by their unique and stable port_id to ensure a stable and unique mapping and
allow future port association modes to be added without requireing any further
internal changes. Existing RRD files are renamend accordingly in discovery and
poller tools to ensure stability of port associations in both modules as we
don't know which might run first after an update.
