Sets the ImmutabilityPolicy to Locked state. The only action allowed on a Locked policy is ExtendImmutabilityPolicy action. ETag in If-Match is required for this operation.

@param resourceGroupName The name of the resource group within the user's subscription. The name is case insensitive.
@param accountName The name of the storage account within the specified resource group. Storage account names must be between 3 and 24 characters in length and use numbers and lower-case letters only.
@param containerName The name of the blob container within the specified storage account. Blob container names must be between 3 and 63 characters in length and use numbers, lower-case letters and dash (-) only. Every dash (-) character must be immediately preceded and followed by a letter or number.
@param ifMatch The entity state (ETag) version of the immutability policy to update. A value of "*" can be used to apply the operation only if the immutability policy already exists. If omitted, this operation will always be applied.
@param serviceCallback the async ServiceCallback to handle successful and failed responses.
@throws IllegalArgumentException thrown if parameters fail the validation
@return the {@link ServiceFuture} object
