J Logan b3b5c3e609 Use labels instead of id to discriminate the builtin network. (#1123)
- Closes #1122.
- Adds placeholder ManagedResource and unit tests. Nothing is using
these yet.
- Adds system-defined resource labels for owning plugin and resource
role. The system discriminates the builtin network using role "builtin".
- Adds builtin role when creating builtin network at startup, and
ensures that a preexisting network with ID "default" gets updated with
the role label.
- Replace all network ID checks for "default" with the builtin role
check.
- Adds "builder" role to builder VM.

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

## Motivation and Context
Role and owner labels should make cross-cutting resource policy easier
to implement.

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