feat(core): support load vertex/edge snapshot

[Radeity]

Purpose of the PR

• close #239

Main Changes

• Use MinIO to store snapshot files, and add MinIO configuration to build the MinIO client.
• Add SnapshotManager to handle snapshot load and write.

Verifying these changes

• [ ] Trivial rework / code cleanup without any test coverage. (No Need)
• [ ] Already covered by existing tests, such as (please modify tests here).

• [x] Need tests and can be verified as follows.

• For my LOCAL test, I deploy MinIO in standalone mode first. Then I test all possible scenarios when using this feature. And here's my testing results:

  当前无快照可读   read snapshot	write snapshot	期望状态	check
  true	false	FAIL	✅
  false	true	不读快照，成功写快照	✅
  true	true	FAIL	✅
  false	false	普通的一次执行（default）	✅

  当前有快照可读 read snapshot	write snapshot	期望状态	check
  true	false	成功读快照，不写新快照	✅
  false	true	不读快照，更新快照	✅
  true	true	成功读快照，不写新快照	✅
  false	false	普通的一次执行（default）	✅

In later PR, I will support to deploy MinIO as internal storage. Then, I will add UT to replace manual test results.

Later PR (Task)

• [x] Use helm to deploy MinIO together with Operator, and then user can use snapshot feature out-of-the-box.
• [ ] Add UT after MinIO is available in test environment (after the first task).
• [ ] Add doc.
• [x] Add license.

Does this PR potentially affect the following parts?

• [ ] Nope
• [x] Dependencies (add/update license info)
• [x] Modify configurations
• [ ] The public API
• [ ] Other affects (typed here)

Documentation Status

• [x] Doc - TODO
• [ ] Doc - Done
• [ ] Doc - No Need
