Closes https://github.com/ray-project/ray/issues/24300
Adds a field to the job submission snapshot that matches the job name in the existing snapshot. Before this PR, the job submission name was camelcased because all snapshot keys are automatically camelcased. This PR allows jobs from the old job field to be linked to ones in the new job submission snapshot.
`test_job_submission` has become [flakey](https://flakey-tests.ray.io/) due to timeout. This change increases the timeout in `test_failed_job_status` from 10 to 25 seconds.
The existing Job info in the cluster snapshot uses the old definition of Job, which is a single Ray driver (a single `ray.init()` connection).
In the new Job Submission protocol, a Job just specifies an entrypoint which can be any shell command. As such a Job can have zero or multiple Ray drivers. This means we should add a new snapshot entry corresponding to new jobs. We'll leave the old snapshot in place for legacy jobs.
- Also fixes `get_all_jobs` by using the appropriate KV namespace, and stripping the job key KV prefix from the job ID. It wasn't working before.
- This PR also unifies the datatype used by the GET jobs/ endpoint to be the same as the one used by the new jobs cluster snapshot. For backwards compatibility, the `status` and `message` fields are preserved.
For public SDK APIs, change the import path from
```python
from ray.dashboard.modules.job.common import JobStatus, JobStatusInfo
from ray.dashboard.modules.job.sdk import JobSubmissionClient
```
to
```python
from ray.job_submission import JobStatus, JobSubmissionClient
```
`JobStatus`, `JobStatusInfo` and `JobSubmissionClient` were the only names referenced in the SDK doc so far, but we can add more later as they appear.
Currently, GCS KV client only has blocking API. Calling them from dashboard event loop can block other operations for many seconds, leading to failures such as taking too long (> 2min) to submit a job and making nightly tests fail (#21699). This PR offloads the blocking work to a separate thread. Implementing async GCS KV API will be done in the future.
After this change in GCS bootstrapping mode, Redis no longer starts and `address` is treated as the GCS address of the Ray cluster.

This is part of gcs ha project. This PR try to bootstrap dashboard with gcs address instead of redis.
