feat: Add dynamodb_client as new option

[FopherC]

Follow up of: #19 (Closed)

Summary

This PR introduces a new option dynamodb_client to the DynamoDb integration, allowing developers to reuse an existing DynamoDbClient instance. This enhancement provides more flexibility and control over the DynamoDB client configuration.

Changes

1. New Option Added:

   • dynamodb_client: Allows passing an already-configured DynamoDbClient instance. If specified, this will cause all other options except dynamodb_prefix and dynamodb_table to be ignored.

2. Updated DynamoDbFeatureRequester Constructor:

   • Modified the constructor to accept the dynamodb_client option and use it if provided.

3. Documentation:

   • Updated the PHPDoc comments in DynamoDb to reflect the new option and provide usage examples.

Usage

Developers can now configure the feature_requester with an existing DynamoDbClient instance as shown below:

$dynamoClient = new Aws\DynamoDb\DynamoDbClient($settings);
$fr = LaunchDarkly\Integrations\DynamoDb::featureRequester([ 'dynamo_client' => $dynamoClient ]);
$config = [ 'feature_requester' => $fr ];
$client = new LDClient('sdk_key', $config);
