Updates to improve blobstore.clj.

* New function blob2 exposes many more options for creating blobs.
* Updated functions that use blob to use blob2.
* New functions sign-get, sign-put, and sign-delete replace the
  functionality of sign-blob-request.
* Added tests.
* Deprecation metadata added to blob and sign-blob-request.
