[FLINK-25402] Introduce working directory for Flink processes

[tillrohrmann]

This PR implements FLIP-198. It consists of several commits that implement the proposed changes:

b70bdca: Make JobManager process resource id configurable via jobmanager.resource-id

This commit introduces a new configuration option jobmanager.resource-id to control the ResourceID of the JobManager process.

308bb99: Introduce ClusterOptions.PROCESS_WORKING_DIR_BASE for configuring a process directory

This commit introduces the configuration options process.working-dir, process.jobmanager.working-dir and process.taskmanager.working-dir to configure a working directory for the JobManager
and TaskManager process. The resulting working directory will be <WORKING_DIR_BASE>/jm_<RESOURCE_ID> and <WORKING_DIR_BASE>/tm_<RESOURCE_ID>.

45d92bb: Clear tmp directory when setting up the working directory

This commit introduces a tmp directory that will be created in each working directory. Moreover, this tmp directory is cleaned whenever the process restarts.

f51113f: Let taskmanager.state.local.root-dirs default to <WORKING_DIR>/localState

This commit makes <WORKING_DIR>/localState the default for taskmanager.state.local.root-dirs. That way the local state will be stored in the working directory if not explicitly configured.

dd6db5f: Set state.backend.rocksdb.localdir to default to <WORKING_DIR>/tmp

This commit makes <WORKING_DIR>/tmp the default for state.backend.rocksdb.localdir if not explicitly configured. This is a behaviour change because before the RocksDB local dir would default to io.tmp.dirs. With this change, the default RocksDB working directory is colocated on the same volume as the local state directory.

Haven't gone through the whole PR, just care about how to handle multi directories from java.io.tmpdir property.

Thanks a lot for the review @zentol. I've addressed most of your comments. The one I only addressed by commenting on it, I've left unresolved. I've pushed and update (unfortunately I screwed up and had to force push :-( ). PTAL.

[tillrohrmann]

@zentol I've update the PR. Hopefully, I have addressed all your comments. PTAL.

[Myasuka]

Please take a look at my comment to shuffle the tmp directories with multi disks.

[zentol]

+1 from my side.

[tillrohrmann]

Thanks for your reviews @Myasuka and @zentol. I've addressed all your comments and pushed an updated version. If AZP gives green light, then I will merge it later.

[Myasuka]

Thanks for the update! LGTM.
