iidm-api and iidm-converter-api modules merging

[geofjamg]

• Do you want to request a feature or report a bug?
  A feature.

• What is the current behavior?
  We have 2 differents Maven modules for IIDM API and IIDM converter API. The first one is responsible for network model API and second one for network import/export plugin API.

• If the current behavior is a bug, please provide the steps to reproduce and if possible a minimal demo of the problem
  N/A

• What is the expected behavior?
  N/A

• What is the motivation / use case for changing the behavior?
  2 motivations:

  • simplification: iidm-converter-api is never add as a dependency on its own and it is indissociable to iidm-api. It would be simplier for users to only have to include iidm-api.
  • my main motivation is to be able to write this which is a more Java idiomatic design and more natural for developpers:

Network n = Network.load("/tmp/n.zip");

instead of

Network n = Importers.load("/tmp/n.zip");

• Please tell us about your environment:

  • PowSyBl Version: 2.4.0-SNAPSHOT
  • OS Version: Linux

• Other information (e.g. detailed explanation, stacktraces, related issues, suggestions how to fix, links for us to have context, eg. stackoverflow, gitter, etc)
