This PR optimize the request count of oras blob delete and oras manifest delete when using against a remote registry.

When deleting a manifest via tag from registry, the requests are optimized as below:

request #1: GET token (scope: pull) - 200
request #2: HEAD manifest tag- 200
request #3: GET manifest digest- 200
request #4: DELETE manifest digest 401
request #5: GET token (scope: delete, pull) - 200
request #6: DELETE manifest digest - 202

After
request #0: HEAD manifest tag- 401
request #1: GET token (scope: pull, delete, push) - 200
request #2: HEAD manifest tag- 200
request #3: GET manifest digest- 200
request #4: DELETE manifest digest - 202

Same for oras blob delete.
