v2 - Params builders do not supply default TransformationManager

[scottgerring]

Consider for instance SSMProvider - if a TransformationManager is not supplied, a default will not be provided. You can contrast this with CacheManager.

powertools-lambda-java/powertools-parameters/powertools-parameters-ssm/src/main/java/software/amazon/lambda/powertools/parameters/ssm/SSMProviderBuilder.java

Lines 51 to 63 in fb14bcf

	public SSMProvider build() {
	if (cacheManager == null) {
	cacheManager = new CacheManager();
	}
	SSMProvider provider;
	if (client == null) {
	client = createClient();
	}
	provider = new SSMProvider(cacheManager, transformationManager, client);
	return provider;
	}

This causes issues in our parameters example, which will throw due to a lack of TransformationManager:

powertools-lambda-java/examples/powertools-examples-parameters/src/main/java/org/demo/parameters/ParametersFunction.java

Line 59 in fb14bcf

MyObject jsonObj = ssmProvider.withTransformation(json).get("/powertools-java/sample/keyjson", MyObject.class);

powertools-lambda-java/examples/powertools-examples-parameters/src/main/java/org/demo/parameters/ParametersFunction.java

Lines 63 to 64 in fb14bcf

	Map<String, String> secretJson =
	secretsProvider.withTransformation(json).get("/powertools-java/userpwd", Map.class);

What were you trying to accomplish?

Expected Behavior

V2 parameters example should work.

Possible Solution

A default TransformationManager should be provided.
