Allow uploading custom, browsable charts to SageMaker Experiments

[tomaszdudek7]

Describe the feature you'd like
Freshly overhauled SageMaker Experiments only allow you to:

• log_confusion_matrix
• log_roc_curve
• log_precision_recall
• log_metric

which all generate some kind of browsable chart. However, there's no way to create a custom plot or to customize existing ones.

It would be great to allow us to upload custom charts that would be displayed directly in the Experiments UI. Plotly, png, matplotlib - literally anything.

How would this feature be used? Please describe.
log_confusion_matrix, log_roc_curve, log_precision_recall are too specific and log_metric is too inflexible (line chart only). You cannot plot a bar chart, a scatterplot or a histogram.

Describe alternatives you've considered
MLflow, Weights&Biases, Neptune.ai, ...

We also need this functionality to help us move from mlflow to sagemaker. Specifically, mlflow like functionality where custom metrics and artifacts can be saved for each experiment would be ideal. Would also be nice to have this functionality in the model registry.
