[Devel] [PATCH RHEL7] configs: set overlayfs nfs_export option to true

[Vasily Averin]

Kostja, Den,
could you please confirm,
are we going to enable config options disabled in original RHEL7?
It is tricky, because Red Hat did not tested it, 
its code can be broken right now or can get broken after following major updates.
Are we going to prepare and run some special tests for overlayfs?

Also, I would like to see any explanation why it is required,
bug explain nothing.

Thank you,
	Vasily Averin
