Mappings: Wait for mappings to be available on the primary before indexing.
In some cases it might happen that a mapping which is already available on the master node is not available yet on the node that holds the primary shard. This commit changes indexing on the primary shard so that if a dynamic update is triggered then the index operation is re-tried until required mappings are available locally (using cluster state observing).
