Bad definition for Checksum type
For both `/src/SOL003/General_Definitions/SOL003_def.yaml` and `src/SOL002/General_Definitions/SOL002_def.yaml`
They not have the proper definition for the Checksum type
```yaml
Checksum: #no definition found
description: >
Cheksum description
type: string
```
That may be because SOL003 and SOL002 do not define the type by themselves. They refer to SOL004 instead. Incorrectly, I’ll add, as this was moved into SOL013 as of NFVSOL(20)000237r1. Anyway, the proper definition is now in SOL013 section 7.1.7
The yaml equivalent of the defintion would be
```yaml
Checksum:
description: Description should be in sync with SOL013 7.1.7
type: object
required:
- algorithm
- hash
properties:
algorithm:
description: Description should be in sync with SOL013 7.1.7
type: string
hash:
description: Description should be in sync with SOL013 7.1.7
type: string
```
