Bug: DynamoDBProvider not tokenizing projection values/names correctly

[dreamorosi]

Expected Behaviour

As a customer, when using the DynamoDBProvider part of the Parameters utility, I want to be able to retrieve values from a DynamoDB Table that uses any of the reserved words as attribute name.

In order to allow this, the provider should be able to transparently tokenize these words under the hood.

Current Behaviour

At the moment, using any of the reserved words as attribute name causes the SDK client to throw an error as they are not tokenized.

Code snippet

const provider = new DynamoDBProvider({
  tableName: 'some-table',
  valueAttr: 'value' // <- this is a reserved word
});

Possible Solution

Use the ExpressionAttributeNames field in the query requests.
