Update storage-aws.md on obsolete aws tags argument. (#2564)

Table manager can automatically add AWS tags to created DynamoDB tables.

Previously this was done using a command line argument like “-dynamodb.index-table.tag=foo=bar” but this moved onto the schema configuration in PR #2221

This PR updates this old reference on the cli argument.
