[FLINK-5046] [tdd] Preserialize TaskDeploymentDescriptor information In order to speed up the serialization of the TaskDeploymentDescriptor we can pre serialize all information which stays the same for all TaskDeploymentDescriptors. The information which is static for a TDD is the job related information contained in the ExecutionGraph and the operator/task related information stored in the ExecutionJobVertex. In order to pre serialize this information, this PR introduces the JobInformation class and the TaskInformation class which are stored in serialized form in the ExecutionGraph and the ExecutionJobVertex, respectively.
