Cleanup SDMetrics to only accept SDV 1.0 metadata format

[npatki]

Problem Description

The SDMetrics library accepts metadata in a Python dictionary format. Currently, it is written so that the metadata can be either (a) the older SDV format or (b) the newer SDV format.

Now that we have released SDV 1.0 with its new format, we can now clean up SDMetrics. It no longer needs to accept the older format.

Expected behavior

We can clean up any reports, metrics and visualizations that expect the metadata to be passed in. A (potentially incomplete) list is provided below:

• Quality Report (single and multi table)
• Diagnostic Report (single and multi table)
• NewRowSynthesis Metric
• Visualization Utilities
• Load Demo

Metrics in Beta:

• Sequential ML Efficacy Metrics
• Sequential Detection Metrics
• Single Table Detection Metrics
• Single Table ML Efficacy Metrics
