To have a better developer experience, the y-provider service run in dev
mode, allowing hot reload when a file is modified. To avoid issue with
shared node_modules, they are mounted in a separated volume to not have
then in the local directory.
Improve y-provider image by having the
node_modules as small as possible.
We move split the Dockerfile and
add it to the y-provider folder,
it will be easier to read and maintain.
