Add command for QueryService Repository

[andrea-mucci]

The minos cli must have the following command

minos queryservice set repository

this command must ask:

• which database? ( at the moment we support sqlalchemy as ORM, so we have to propose mysql/postgresql/sqlite )
• database host
• database port
• database name

the cli would create the following files

queries/models.py

from sqlalchemy.orm import declarative_base

Base = declarative_base()

queries/repository.py

from minos.common import MinosSetup, MinosConfig
from sqlalchemy import create_engine
from src.queries.models import Base

class QueryServiceRepository(MinosSetup):

    def __init__(self, *args, **kwargs):
        super().__init__(*args, **kwargs)
        self.engine = create_engine({{ THE URL DATABASE }})

    async def _setup(self) -> None:
        Base.metadata.create_all(self.engine)

    @classmethod
    def _from_config(cls, *args, config: MinosConfig, **kwargs) -> ProductQueryRepository:
        return cls(*args, **(config.query_repository._asdict()) | kwargs)

the CLI must update the config.yml as well

...

query:
  database: database_choosen_by_the_dev_db
  user: postgres
  password: ""
  host: localhost
  port: 5432

And must modify the plkaybooks/create-databse.yaml adding the following information

- name: Create Query Database
  import_playbook: ../../../external/postgres/playbooks/create-database.yaml
  vars:
    db_name: database_choosen_by_the_dev_db
