plugin app manager: add a way to create files:

a `files` field can now be used to create files on the fly. Its value must be a dict where
key are file names, and values are an other dict with file data.

For now file data can only use the `content` key. Value of content will be written to the file.
If a file already exists, it is not overwritten.
