feat: [deploy] improve files logging

[pabloes]

What?

In dcl deploy command:

• Adds a log with number of files and total size
• Add option --log-files to log detailed list of all files and size ordered by size
• fix: [deploy] exceeded size files log
• fix warning on tests about unnecessary await

Why?

• Fixes a bug on exceeded file size error message
• Can help giving support to SDK users
• To check unused files being upload
• To check bigger files being uploaded and analysis for optimization
• To keep control of the number of files being uploaded and the total size
• To check empty files (reported to be problematic)
