🐛 Create intermediate path for resources stored as files. (#94)

The java extension CR defines:
```
    resources:
    - fields:
      - key: maven.settings.path
        name: settings
        path: /shared/creds/maven/settings.xml
      selector: identity:kind=maven
```
`/shared` exists but `creds/maven` needs to be created on demand.

Reported by CI as:
```
 "errors": [
      {
        "severity": "Error",
        "description": "open /shared/creds/maven/settings.xml: no such file or directory"
      }
    ],
```
