Update IronWare sensors & bgp-peers discovery, allow skip_values to target a specific index appended to the OID (#10941)

Browse Source 
* Migrate ironware sensor discovery from php to yaml.

* More sensors, add grouping.

* dynamic_discovery_get_value() becomes getValueFromData()

* Target a specific index with skip_values.

* Improve Brocade BGP session discovery/polling

This commit allows for the correct discovery of BGP sessions
with 32-bit ASNs, IPv6 neighbors using the BGP4V2-MIB which is
based on draft-ietf-idr-bgp4-mibv2-11 and also polls for IPv4
unicast received routes through the FOUNDRY-SN-BGP4-GROUP-MIB.

Copied most of the code from PR#8877 by @Mikeburke14, cleaned
up the code a little bit to match the normal LibreNMS style,
and fixed bgpPeers_cbgp discovery as well as polling for the
ipv4.unicast neighbors.

Note that older Brocade IronWare firmware versions are known
to have multiple defects relating to the BGP4V2-MIB which
might result in certain missing non-established neighbors.
