J Logan 356c8d2f88 Reorganize client libraries. (#1020)
- Closes #461.
- Extract core types into ContainerResources target.
- Extract ContainerNetworkServiceClient from ContainerNetworkService.
- Relocate sandbox client from ContainerClient to
ContainerSandboxServiceClient.
- Relocate ContainerClient to ContainerAPIServiceClient.
- Common structure from services and clients under Source/Services.

Updated project hierarchy:

```
Sources/CAuditToken - audit token access wrapper
Sources/CLI - CLI executable
Sources/ContainerBuild - builder
Sources/ContainerCommands - CLI command implementations
Sources/ContainerLog - logging helpers
Sources/ContainerPersistence - persistent data and system property helpers
Sources/ContainerPlugin - plugin system
Sources/ContainerResource - resource (container, image, volume, network) types
Sources/ContainerVersion - version helpers
Sources/ContainerXPC - XPC helpers
Sources/CVersion - injected project version
Sources/DNSServer - container DNS resolver
Sources/Helpers - service executables
Sources/Services/*/Client - service clients
Sources/Services/*/Server - service implementations
Sources/SocketForwarder - port forwarding
Sources/TerminalProgress - progress bar
```

## Type of Change
- [ ] Bug fix
- [ ] New feature  
- [x] Breaking change
- [ ] Documentation update

## Motivation and Context
The ContainerClient library was a bit of a grab bag. This refactor
applies a more sensible project and library structure for resource data
types, services, and clients.

## Testing
- [x] Tested locally
- [x] Added/updated tests
- [ ] Added/updated docs
