Retry policy now applies to all requests and subscription change status emitted (#451)

feat(retry-policy): retry policy now applies to all requests

The configured retry policy will be used for any failed request.

feat(retry-policy): exponential retry policy used by default for subscribe

By default, the SDK is configured to use an exponential retry policy for failed subscribe requests.

feat(retry-policy): add `None` retry policy

Add type, which should be used to completely disable retries.

fix(subscribe): add missing `subscription change` status

`PNSubscriptionChangedCategory` will be emitted each time the list of channels and groups is
changing.

refactor(network): request retries moved to the network

Automated request retry has been moved into the network layer to handle all requests (not only
subscribed).

refactor(retry-policy): add information about which APIs belong to endpoint

Add more information about which APIs are related to the endpoints, which can be excluded.
