[FLINK-8787][flip6] WIP
WIP
## What is the purpose of the change
*(For example: This pull request makes task deployment go through the blob
server, rather than through RPC. That way we avoid re-transferring them on each
deployment (during recovery).)*
cc: @tillrohrmann
## Brief change log
*(for example:)*
- *The TaskInfo is stored in the blob store on job creation time as a
persistent artifact*
- *Deployments RPC transmits only the blob storage reference*
- *TaskManagers retrieve the TaskInfo from the blob cache*
## Verifying this change
*(Please pick either of the following options)*
This change is a trivial rework / code cleanup without any test coverage.
*(or)*
This change is already covered by existing tests, such as *(please describe
tests)*.
*(or)*
This change added tests and can be verified as follows:
*(example:)*
- *Added integration tests for end-to-end deployment with large payloads
(100MB)*
- *Extended integration test for recovery after master (JobManager)
failure*
- *Added test that validates that TaskInfo is transferred only once
across recoveries*
- *Manually verified the change by running a 4 node cluser with 2
JobManagers and 4 TaskManagers, a stateful streaming program, and killing one
JobManager and two TaskManagers during the execution, verifying that recovery
happens correctly.*
