Description

ExecutionVertexID is now added as a field to ExecutionVertex.

Many components, however, are still creating ExecutionVertexID from ExecutionVertex by themselves. This may lead to more memory consumption of JM. It also slows down the ExecutionVertexID equality check.

We should change them to use the field ExecutionVertex#executionVertexID directly.
