publicIp resourceId needs to know if none is allowed

on the nic resource that consumes the publicIP, does it allow for the none scenario

createUIdef, has a publicIp address control... this control allows for the use of new/existing/none. The resource for that publicIp in mainTempate will have a condition property that allows for new/existing/none.

Any resourceId that references that publicIp resource, must have a condition surrounding it that accommodates for the "none" option. This is usually don't by wraping the resourceId in an if() statement and one of the clauses is json('null').

Also need to account for the publicIpAddress property is an object variable
Also need to account for nested deployments that handle the conditions.
