Expose only services with protocol odata-v2

[oklemenz2]

• [ ] Add option: protocolBased (default false) -> switch default for major version?
• [ ] If service is annotated with odata-v2, then it is exposed, otherwise ignored
• [ ] Service also needs to be served via odata-v4 otherwise redirect does not work
• [ ] Respect protocol in Build task
• [ ] Support arbitrary path definitions (convert e.g. odata/v2/xyz => odata/v4/xyz => odata/v4/abc or /abc)

That means service annotation need to look like this

@protocol: [
  { kind: 'odata-v4', path: 'xyz' },
  { kind: 'odata-v2' }
]

Would result in paths => odata/v4/xyz and odata/v2/xyz Absolute paths (/xyz) would be => /xyz and odata/v2/xyz

Specifying a path for kind odata-v2 is not supported. This is currently not supported, as it is assumed, that the protocol prefix always can be replaced. i.e. odata-v2 => odata-v4 or /

Shifted to major refactoring, implementing an odata-v2 protocol adapter as CDS middleware by rewriting same express request, without additional http call. Version 2.0.0.
