Detailed Description

Key-value manager for the DDS commander.

In order to keep a thread safety of the key-value manager we don't add and remove elements in the data containers on the fly. All key-value records are added during the initialization of the manager based on the information from the topology. When record is deleted it is only marked as deleted without actual deleting it from the container. This approach allows us to have a fast updates and deletes of the records without locking the whole container, only the records which are modifying now are locked.
