Allow disabling restore as a practice

[ngudbhav]

In some applications, it is advised, as a design practice, to disable the restoration of a deleted record and instead create a new record whenever required.

Introducing a new configuration attribute to disable restoration completely will help us enforce this as a practice throughout the codebase.

Please let me know if this idea sounds good. I'd be more than happy to pick up the change.

if its available as optional, I don't see a problem... but I really wonder how popular this will be?
