The one with subscription plugin

Description

This release adds a new plugin type - subscription - which will allow to register subscription plugins.
A subscription plugin will allow to subscribe to new interaction notifications (registered for the given contract) and automatically update the local state.

A new method has been added to the Contract interface -

readStateFor(interactions?: GQLNodeInterface[]): Promise<SortKeyCacheResult<EvalStateResult<State>>>

It allows to read the state of the contract for the passed interactions and is an equivalent of calling readState(undefined, undefined, interactions)

The new subscription plugins are available here.
