refactor(infra): refactor deploy_service from procedural to OOP resources

[guilhem-fry]

Abstracts out the infra into main "components":

• DB
• Cloud Run service
• Load balancers

Each of these components have underlying GCP resources

Each component implements the class AbstractResource Each of them implements the _create method, which is where pulumi is called to create underlying resources

_create will be called automatically when the class is instanciated

e.g

@dataclass
class NewGCPComponent(AbstractResource):
     def _create():
          pulumi.createNewResource()
          pulumi.anotherResource()

NewGCPComponent()
