/**
* This format supports Shared Key authentication for the 2009-09-19 version of the Blob and Queue
* services. Construct the CanonicalizedResource string in this format as follows:
*
* <p>1. Beginning with an empty string (""), append a forward slash (/), followed by the name of
* the account that owns the resource being accessed.
*
* <p>2. Append the resource's encoded URI path, without any query parameters.
*
* <p>3. Retrieve all query parameters on the resource URI, including the comp parameter if it
* exists.
*
* <p>4. Convert all parameter names to lowercase.
*
* <p>5. Sort the query parameters lexicographically by parameter name, in ascending order.
*
* <p>6. URL-decode each query parameter name and value.
*
* <p>7. Append each query parameter name and value to the string in the following format, making
* sure to include the colon (:) between the name and the value:
*
* <p>parameter-name:parameter-value
*
* <p>8. If a query parameter has more than one value, sort all values lexicographically, then
* include them in a comma-separated list:
*
* <p>parameter-name:parameter-value-1,parameter-value-2,parameter-value-n
*
* <p>9. Append a new line character (\n) after each name-value pair.
