Oob ip (devices) (#13013)

* initial oob_ip support for devices

* add primary ip and oob ip checkmark to ip address view

* add oob ip to device view and device edit view

* pep8

* make is_oob_ip and is_primary_ip generic for other models

* refactor oob_ip

* fix oob ip signal

* string capitalisation

* Misc cleanup

 !!! tip
     NetBox will prefer IPv6 addresses over IPv4 addresses by default. This can be changed by setting the `PREFER_IPV4` configuration parameter.
 
+### Out-of-band (OOB) IP Address
+
+Each device may designate its out-of-band IP address. Out-of-band IPs are typically used to access network infrastructure via a physically separate management network.
+
 ### Cluster
 
 If this device will serve as a host for a virtualization [cluster](../virtualization/cluster.md), it can be assigned here. (Host devices can also be assigned by editing the cluster.)
