a69c6d1ec9 [#2272] morph: Do not subscribe to events without listening
All checks were successful
ci/woodpecker/push/pre-commit Pipeline was successful
It led to a neo-go dead-lock in the `subscriber` component. Subscribing to
notifications is the same RPC as any others, so it could also be blocked
forever if no async listening (reading the notification channel) routine
exists. If a number of subscriptions is big enough (or a caller is lucky
enough) subscribing loop might have not finished subscribing before the
first notification is received and then: subscribing RPC is blocked by
received notification (non)handling and listening notifications routine is
blocked by not finished subscription loop.
That commit starts listening notification channel _before_ any subscription
actions.

f037022a7a [#1770] logger: Refactor Logger component
Make it store its internal `zap.Logger`'s level. Also, make all the
components to accept internal `logger.Logger` instead of `zap.Logger`; it
will simplify future refactor.

3a206b5d7a [#1763] morph/event: Write log message about new notification event
Sometimes it is useful to track sidechain events processed by the node.
For example, we need some easy way to look up for log messages about new
epoch notifications.

Make `subscriber.Subscriber` to log names of all events received from
the sidechain notification channel.

8efeba8010 [#833] morph/subscriber: Change value cast for NotificationEventID
`WSClient` of Neo Go v0.97.3 sets value of notification with
`NotificationEventID` to `subscriptions.NotificationEvent` type which wraps
previously used `state.NotificationEvent`.

Change type cast and pull `state.NotificationEvent` structure from new type.

67471a8914 [#798] morph/subscriber: Await for RPC initialization
Remote RPC node might be in the transition state and produce
events from the past. We should avoid listening such nodes.
To do that subscriber component can await minimal height of
remote node. If minimal height is not reached, then throw
error.
