Comments still reference deleted function Get-ServiceNowUser

[jbalcorn]

New-ServiceNowIncident.ps1 still has Get-ServiceNowUser in the instructions. Very confusing.

# sys_id of the caller of the incident (user Get-ServiceNowUser to retrieve this)
        [parameter(Mandatory)]
        [string] $Caller,

This is a carryover from the older days. Folks shouldn't look in code for function help. We need to have traditional builtin help provide this data.
