Describe the bug
Client-side encrypted upload (BlobClient.Upload()) alters the actual Dictionary<string, string> of metadata passed by the user as blob metadata.

Expected behavior
User-provided dictionary should be un-modified. Upload() should clone the dictionary and modify the clone as necessary for encryption purposes

Actual behavior (include Exception or Stack Trace)
Upload() sets the value of encryptiondata in the user's metadata object.

To Reproduce
Upload blob content with metadata while client-side encryption is enabled. Observe dictionary before and after upload.

Environment:

  • Azure.Storage.Blobs 12.10.0
  • net461 Windows 10
  • Visual Studio 2019 16.11.5
