Unable to use ContainerCredentialsProvider CredentialsProvider for Multilang project

[stabl-gjn]

This is more a issue with the dependencies (specifically awssdk-java-v2) than with amazon-kinesis-client-python itself but as this project defines what version of dependencies to use and the issue has already been resolved upstream, i created the ticket here.

When setting ContainerCredentialsProvider as AwsCredentialsProvider in the properties file passed to KCL (v3.0.1) it fails with:

Attempting to construct class software.amazon.awssdk.auth.credentials.ContainerCredentialsProvider
Unable to construct any provider with name ContainerCredentialsProvider

This appears to be a oversight in awssdk-java-v2, as the ContainerCredentialsProvider does not contain a create function for the version this project is using (v2.25.64;

amazon-kinesis-client-python/pom.xml

Line 5 in 76a1e3f

<awssdk.version>2.25.64</awssdk.version>

).

Code in awssdk-java-v2 v2.25.64:
https://github.com/aws/aws-sdk-java-v2/blob/76d2819f93a21c7600e0e53e3f13345ade1c8387/core/auth/src/main/java/software/amazon/awssdk/auth/credentials/ContainerCredentialsProvider.java

The function has been later introduced with: aws/aws-sdk-java-v2@0043e38

The multilang implementation relies on this function to be present if no string only (or blank) constructor is available on the class:

https://github.com/awslabs/amazon-kinesis-client/blob/4492e1e206198f9d01af3c0a954ffe64907e8b11/amazon-kinesis-client-multilang/src/main/java/software/amazon/kinesis/multilang/config/AwsCredentialsProviderPropertyValueDecoder.java#L83-L105

As the constructor expects a BuilderImpl it will probably not be called (only called with string args) and a create does not exist for the specific version of awssdk-java-v2.
