for signing a Table service request under the Shared Key authentication scheme.

@param address
the request URI
@param accountName
the account name associated with the request
@param method
the verb to be used for the HTTP request.
@param contentType
the content type of the HTTP request.
@param contentLength
the length of the content written to the outputstream in bytes, -1 if unknown
@param date
the date/time specification for the HTTP request
@param conn
