Add sample scripts for ValueFinder and changelink

[akaash2512]

Add sample scripts for two features:

1. Valuefinder
2. ChangeLinks

Value Finder:

This script helps to find occurrences of a property value in given path

What it does

• recursively traverse the node structure beneath the given root node
• find occurrences of the given property value
• define exceptions in property values that shall not be listed, e.g. in the case of the http-to-https switch we can explicitly hide property values containing "google" since we know that google already supports https
• restrict results to a list of resource types or vice versa exclude a list of resource types

Change Links

• This script enables authors/admins to change link

What it does

1 - Searchable url, 2 - target url, 3 - destination url
Example:
1 - www.swisscom.ch/mobile/online/app/MobileCard
2 - https://www.swisscom.ch/mobile/online/app/MobileCard?mode=overview&lang=en
3 - https://www.swisscomch/myswisscom/dashboard
