Creates an instance of BlobServiceClient from connection string.

@param connectionString - Account connection string or a SAS connection string of an Azure storage account.
                                 [ Note - Account connection string can only be used in NODE.JS runtime. ]
                                 Account connection string example -
                                 `DefaultEndpointsProtocol=https;AccountName=myaccount;AccountKey=accountKey;EndpointSuffix=core.windows.net`
                                 SAS connection string example -
                                 `BlobEndpoint=https://myaccount.blob.core.windows.net/;QueueEndpoint=https://myaccount.queue.core.windows.net/;FileEndpoint=https://myaccount.file.core.windows.net/;TableEndpoint=https://myaccount.table.core.windows.net/;SharedAccessSignature=sasString`
@param options - Optional. Options to configure the HTTP pipeline.
