Add Spring Boot properties to connect to remote Dapr Endpoints

[salaboy]

Spring Boot Application can use Spring Boot properties to set up values for the DaprClient, DaprWorfklowClient to use.
Add a section in the Spring Boot docs to cover these properties.

dapr.client.httpEndpoint=<Your Remote Project HTTP Endpoint>
dapr.client.grpcEndpoint=<Your Remote Project GRPC Endpoint>
dapr.client.apiToken=<Your Remote APP ID API Token>

The PR that was merged didn't covered the properties stated here:

dapr.client.httpEndpoint=<Your Remote Project HTTP Endpoint>
dapr.client.grpcEndpoint=<Your Remote Project GRPC Endpoint>
dapr.client.apiToken=<Your Remote APP ID API Token>

We might need to unify these properties, but these are the ones used to override full endpoints.
@mcruzdev can you add this too?

Hi @salaboy, I can add it.

Should I overwrite that kebab-case? It can be very weird to the use.

What I need to use? dapr.client.httpEndpoint or dapr.cleint.http-endpoint?

I am saying it because Spring in the application properties supports both (camelCase and kebab-case)
