[krtkvrm]

The scope of this PR is also to refactor Org Service.
from:

type OrganizationService interface {
	GetOrganization(ctx context.Context, id string) (org.Organization, error)
	CreateOrganization(ctx context.Context, org org.Organization) (org.Organization, error)
	ListOrganizations(ctx context.Context) ([]org.Organization, error)
	UpdateOrganization(ctx context.Context, toUpdate org.Organization) (org.Organization, error)
}

To:

type OrganizationService interface {
	Get(ctx context.Context, id string) (modelv1.Organization, error)
	Create(ctx context.Context, org modelv1.Organization) (modelv1.Organization, error)
	List(ctx context.Context) ([]modelv1.Organization, error)
	Update(ctx context.Context, toUpdate modelv1.Organization) (modelv1.Organization, error)
}

@krtkvrm I think we don't need to version internal models. So would suggest removing versioning from here.

[krtkvrm]

yeah.. makes sense 👍
