[Storage-blob] ContainerClient encodes blobName including folder which produces are problematic url

• Package Name: storage-blob

Describe the bug The problem is this line. It encodes the blobName, but the blobName can also include a folder, like folderA/blob.txt.

This produces the following URL: https://mystorageaccount.blob.core.windows.net/my-container/folderA%2Fblob.txt

This is fine most of the time, but if you want this to work with an Apache proxy you have to set AllowEncodedSlashes, see Apache docs.

To Reproduce Steps to reproduce the behavior:

const sasUrlToContainer = 'https://mystorageaccount.blob.core.windows.net/my-container?[sasQueryParameters]';
const blobName = 'folderA/blob.txt';
const client = new ContainerClient(sasUrlToContainer);
const blobClient = client.getBlockBlobClient(blobName);
const result = await blobClient.download();

Expected behavior The encoding should only include the filename but not the folder name.

The fix has been released in @azure/storage-blob@12.12.0.

.NET does not encode ‘/’. We will want to do the same too: https://github.com/Azure/azure-sdk-for-net/blob/0ce8e17b4dee01d7d3c2e0aff6977706d448eee0/sdk/storage/Azure.Storage.Common/src/Shared/StorageExtensions.cs#L12-L28
