Un-deprecate JSONRestconfService(Impl)
Patch https://git.opendaylight.org/gerrit/#/c/56391/ deprecated
JSONRestconfService and JSONRestconfServiceImpl however no reason
was given in the patch message (in fact the patch was about fixing
checkstyle violations) nor were any comments added to the classes
as to why they're deprecated.
There really shouldn't be any reason to deprecate these classes
as they are useful and are used in applications. Therefore I remove
the @Deprecated annotation.
