Renew operations

• [Deprecated] The original operation implementation is deprecated, so the below options become deprecated.
  • operation: Use query option or scan option instead.
  • limit: Use query.batch_size option or query.batch_size instead.
  • scan_limit: Use query.batch_size option or query.batch_size instead.
  • record_limit: Use query.limit option or query.limit instead.
  • filters: Use query.filter_expression option or query.filter_expression instead.
• [New Feature] Introduce new options scan, query to support all configurations for Dynamodb Scan/Query Operation API except legacy configurations.
  • NOTE: This operation stores null AttributeValue as null, though, in the deprecated operation, null is converted arbitrarily. (string -> empty string, long -> 0, double -> 0.0, boolean -> false)
  • NOTE: This operation stores timestamp values by parsing user-defined format, though the deprecated operation skips storing values when the column type is defined as timestamp without any errors.
  • NOTE: This operation can convert the specific type of the attribute that you specify in column.attribute_type to Embulk types, though the deprecated operation can only convert Embulk types that match a particular Dynamodb Attribute type.
• [Enhancement] You can store each dynamodb item as JSON, so "columns" option becomes optional.
• [Enhancement] You can specify the AttributeValue type (like "S", "N", "SS" and so on) used when converting AttributeValue to Embulk type.
• [BugFix] Avoid NullPointerException when Type N AttributeValue has null in the deprecated operation.
• [Enhancement] Examples work without real Dynamodb.
• [Enhancement] Add more examples.
