SOLR-7609: Validate the version is present on follower replicas when adding
documents (#1504)
* Add the version check on additions to fail in case we are not leader and
version = 0. (to match delete flows)
* Change error status from BAD_REQUEST to INVALID_STATE to allow for retries.
* Remove a 'cmd' variable - this is just minor readability refactoring, I tried
to avoid changing the code as much as possible
* Update the ShardSplitTest to keep track of exceptions happening during the
concurrent adds and deletes and fail if needed.
*Fix bad null validation
