Rename metadata to properties

[roznawsk]

Rename Component.Metadata to Component.Properties

Motivation: The name "Metadata" interpreted as Data about Data is inaccurate in this case, since the Metadata structure contains information about component, such as playable?, lowLatency? or targetWindowDuration in the case of HLS component.

I think that the proposed name Properties is much better in this case and a lot more self-explanatory.

Acknowledging the stipulations set forth:

• [ ] I hereby confirm that a Pull Request involving updates to the Software Development Kit (SDK) has been smoothly merged, currently awaits processing, or is otherwise deemed unnecessary in this context.

The changes to the SDKs will follow after implementing the File Endpoint

• [x] I also affirm that another Pull Request, specifically addressing updates to the documentation body (commonly referred to as 'docs'), has either been successfully incorporated, is in the process of review, or is considered superfluous under the prevailing circumstances.
