Add SharedKeyLite auth support to blob service

[giggio]

My use case is the same as previous users, I'm using a JClouds app, which still uses SharedKeyLite. More specifically, https://github.com/gaul/s3proxy. The idea is to use the S3 api to save blobs to Azure Storage. I took the work from #402 and updated it to the latest changes. I haven't found test cases, but I have manually tested it with Azure Storage Explorer and and a s3proxy. It was not working on s3proxy, and now it is.

Superseedes #402. Closes #378.

The pipeline is failing for reasons not related to this PR. All recent PRs are failing with the same problem. I sent another PR (#1755) to fix it.

Thanks for contribution! Can you help add BlobSharedKeyLiteAuthenticator.ts for SharedKeyLite logic instead of modifying BlobSharedKeyAuthenticator.

BTW, we need coverage and test cases for the new SharedKeyLite.

Sure! Can you point me to similar tests, so I can move forward?

You can reference this test case, it use a pipeline policy to set header "Origin" on the request just before it send to server. You can also write your own pipeline policy to set the header "Authorization" to sharedkeylite and its signature, just before the request is sent to server. https://github.com/Azure/Azurite/blob/73ed83c2dd07a4fc97f21b9d50450bef8b5c26b0/tests/blob/blobCorsRequest.test.ts#L594

The PR has pending for a long time. Would you please help to add test case for the change and fix the conflict? Then we can continue the review process of this PR.

Any news on this PR? We recently had code fail and lost a couple of hours until we realized Azurite is not implementing SharedKeyLite auth (which is easier to implement on custom clients like small IoT devices than the full auth).

No, the requested refactoring is too large for me to be able to take it over right now. I'm closing it.
