Dev deployer reorg

Context

linked to issue https://gitlab.eclipse.org/adamaroni/aidge_federated/-/issues/7

A new step to a better deployer : The deployer code was reorganized for a better understanding of the deployment steps, explaning better how the info contained in deployer.yaml is used. The build directory was reorganized a bit, too, for better organization in multiple language contexts.

Main modified files

• examples/federated_learning_skeleton/deployer.rb, the code is much shorter and is intended to explain better what information is fetched from deployer.yaml

• examples/federated_learning_skeleton/deployer.yaml the tpl part was modified a bit for better automation of build scripts

• examples/federated_learning_skeleton/deployer_functions.rb a new file that contains the content of the functions called in deployer.rb

• Other files : relative paths to libraries were updated
