DaprClientProperties don't have defaults set

[salaboy]

Expected Behavior

When starting a Spring Boot application without setting DaprClientProperties, these should be instantiated with the default Dapr values.

Http Endpoint should be: "http://localhost" by default if not overriden
GRPC Endpoint should be: "localhost" by default if not overriden
HTTP port should be: 3500
GRPC port should be: 50001
API token should be: null (unless specified)

Actual Behavior

Properties instanciated with empty values for http and grpc endpoints and ports.
