Add a select box to the device SNMP edit page in the WebUI to update
the port association mode of a device.

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.

This makes the following changes:
- Record per-module performance data in the same measurement as overall poller-perf
- Add tags to distinguish modules
- Update rrd filenames
- Use stacked graph for poller modules

DESCRIPTION
"The version number of IEEE 802.1Q that this device
supports. Reported as 1 by VLAN Bridges that support
only SST operation, and reported as 2 by VLAN Bridges
that support MST operation."

This Authentitation / Authorization module provides the ability to let
the webserver (e.g. Apache) do the user Authentication (using Kerberos
f.e.) and let libreNMS do the Authorization of the already known user.
Authorization and setting of libreNMS user level is done by LDAP group
names specified in the configuration file. The group configuration is
basicly copied from the existing ldap Authentication module.
To save lots of redundant queries to the LDAP server and speed up the
libreNMS WebUI, all information is cached within the PHP $_SESSION as
long as specified in $config['auth_ldap_cache_ttl'] (Default: 300s).

Implements the CISCO-CLASS-BASED-QOS-MIB to retrieve QOS counters from Cisco devices.
Policy and Class-map details are collected and stored in the database.
Details are presented on a new "CBQoS" tab of the interface that the policy is applied to.
Includes a policy selector that allows you to select which policy-map to show graphs for.
Each class-map has its own rrd file, in which 3 metrics are stored: Bytes, QoS Drops, Buffer Drops.
This can produce a LOT of rrd files.
As an example:
A Cisco 4500 series switch, running MQC on 200 ports. Each port has a common 5 class queueing policy applied, this creates 1000 (5 x 200) RRD's.
Because of this I have currently set:
```
$config['discovery_modules']['cisco-cbqos'] = 0;
```
Includes function snmpwalk_array_num, which performs a numeric SNMPWalk and returns an array containing $count indexes
One Index:
From: 1.3.6.1.4.1.9.9.166.1.15.1.1.27.18.655360 = 0
To: $array['1.3.6.1.4.1.9.9.166.1.15.1.1.27.18']['655360'] = 0
Two Indexes:
From: 1.3.6.1.4.1.9.9.166.1.15.1.1.27.18.655360 = 0
To: $array['1.3.6.1.4.1.9.9.166.1.15.1.1.27']['18']['655360'] = 0
And so on...
