nso_verify handle leaf-list in 4.5 and identityref (#37393) (#37634)

* nso_verify handle leaf-list in 4.5 and identityref (#37393)

NSO verify did not handle leaf-list value verification in 4.5 and
later due to changes made for configuration writing made.

map prefix for identityref types in verification.
(cherry picked from commit 6308047dc9)

* Remove timeout
