XD-1271 Enable Endpoint RequestHandlers

- By default, Boot's EndpointWebMvcAutoConfiguration disables
Endpoints request handlers if the management port set to '0'
If we remove the explicit setting of management port to '0' then
the management port will use the server properties port and
the Endpoint request handlers are enabled.
- Also, removed unused "memory" profile

  msgs.

- Adds a basic script test to check notifications
