Remove default scheduler-host-address

[mikeee]

Expected Behavior

The scheduler streaming client should not be initialised by default with the run command following changes in 1.14.1. This makes it consistent with the multi-app run for example.

Actual Behavior

A scheduler client connection is initialised and failing to connect.

Steps to Reproduce the Problem

Command:

dapr run --app-id testapp

Result:
Scheduler client initialised with localhost:50006 and failing to connect repeatedly

Release Note

RELEASE NOTE: UPDATE Scheduler client is no longer initialised by default

That is an interesting one because connecting to scheduler by default was done because it is needed for Jobs API to work, even as an alpha feature. Maybe, we change runtime so it does not fail if cannot connect to scheduler? It would also mean that Jobs API is not available to those instances either.
