DNS provisioning needs to allow foreign ID to be a hash of IP address instead of nodeLabel if administrator so chooses

Details

Description

In some cases, the opennms administrator may choose to have the foreign ID be tied to IP address instead of node label. for DNS provisioned nodes The implications of using the IP address to create a hash for the foreign ID are:
1. if a node changes names but keeps the same address it will NOT be deleted and recreated as a new node.
2. If a node changes ip addresses but keeps the same node label, it WILL be deleted and recreated as a new node created.
The behavior is just the opposite when using the nodeLabel. Default should be to use the node label, which is the case in existing releases.

When provisioning from DNS, the foreignID for a node is a hash of the nodeLabel. Add an
optional field to the query string of the DNS URL, like so:

dns://my-dns-server/myzone.com/portland/?expression=^por-.*&foreignIdHashSource=someString

if someString contains 'ip' or 'addr' the IP address of the node will be used to generate the hash for the foreignID

if someString contains 'label' or 'name' the nodeLabel will be used to generate the hash. This is the same as the default, and the original behavior.

if someString contains both 'label' or 'name' AND 'ip' or 'addr' the hash will be generated from the string concatenation of the nodeLabel and the IP address.
