explore removing rxjs as a dependency in @tdm/data

[shlomiassaf]

Currently, @tdm/data depends on the RXJS observables library and uses it to manage logic and workflow.

Since it is a core library, it's better not to enforce a 3rd party library that might be used on an application only by @tdm/data.

RXJS is used in 3 places:

Events

The events are completely RX based, there is one event stream (hot) from which all events come from.

Effort: Hard

Plugins (resource-control)

Extends the root event stream and filter events based on their instance origin.
From there, each instance's event stream is split into logical events that expose stream such as busy, self etc.

Effort: Hard

Action controller (action flow)

The actions controller handles an action flow, the whole flow is RX based.
In addition, each adapter must implement an execute function that returns an observable.
