[backport] [FLINK-5046] [tdd] Preserialize TaskDeploymentDescriptor
information
This is a backport of #2779 for the release 1.1 branch.
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 TaskInformration class which are stored in serialized form in the
ExecutionGraph
and the ExecutionJobVertex, respectively.
Fix for release-1.1
