Add capability checks for operations

[Xuanwo]

In #2060, we added a new concept of Capability in operator. So far, we only do checks during integration tests.

In fact, we can do this check in CompleteLayer.

Before we start any operation, we should check the Capability first. If not supported, we should return an unsupported error directly.

Tasks

• Add capability checks for operations
• Add strict mode in Operator
• Add capability checks for OpXxx
  • If strict enabled, return unsupported error if the arg is not supported

Thanks a lot! Let me add more context for this issue.

[unixzii]

Sounds great. I will file a draft PR first, and continue to work on it once the design is confirmed by reviewers.

The whole story is not yet finished, we still need this issue to track strict mode. @Xuanwo could you reopen it?

Hi, @unixzii, Test for gcs failed https://github.com/apache/incubator-opendal/actions/runs/5280208287/jobs/9551992175

Would like to take a look? Thanks in advance.
