[PBI] Implement ParallelsService Websockets messages

[cjlapao]

Description

We need to implement the events that we receive from the ParallelsDesktop event emitter as Websockets push notifications to all listening clients on the ParallelsDesktop Inbox. This will help consumers to react to changes in the VM states or any other change.
The message should contain the vm object that it is relating to, this will avoid the client to call any API to get the data, it will go in the body of the push message but we need to make sure the object is manageable so we need to trim the JSON object to the minimum possible

What do we need?

• A inbox for the ParallelsDesktop for clients to subscribe
• All events from the PDfM Event Emitter to be pushed to that inbox
• Each event will have the VM id the type of change and the VM Body

User Story

As a user I want to be able to subscribe to the ParallelsDestop inbox and receive the updates of the changed state in real time
As a developer I want to be able to provide the new states to update the clients in real time changes in the consumer VM states
