F5 multi partitions failover support

currently, only f5 with 1 partition is supported.
librenms using this OID to get the failover status of the device:
which returns “active”(value number 4) for greater than 1 partition is currently active.
which is not very well suited, for example, we have 6 partitions, 1 device with 1 partition active/5 standby, on the other device 5 partitions active/1 standby.
the OID is returning 4(active) for both of them.
we can use this OID which returns String for example: “1/6 active”
