[4.0] API for Media

[Razzo1987]

Describe the solution you'd like

A set of API for:

• upload imege (or media) in "imeges" directory
• upload imege (or media) in sub-directory
• create a new folder/subfolder in "images" directory
• list the folder tree of the "imeges" directory
• list the media in directory/subdirectory

Additional context

With these API it will be possible to insert images in Joomla that can then be used in the creation of the articles

I'll be happy to test, when and if this is done.
