In order to configure the AdditionalImageStores we have to change the config file.
I'd like to have the possibility to add additional image stores just adding a file inside a folder like /etc/containsers/additionalstore.conf.d. In this way I don't have to modify the configuration file if I add a new image store layer.

The content of this folder should be smthg like:

• /etc/containsers/additionalstore.conf.d/001-store-app-a
• /etc/containsers/additionalstore.conf.d/002-store-app-b
• /etc/containsers/additionalstore.conf.d/003-store-app-c

where each file contains the real path of the store
