Use MatomoModule and MatomoTracker in external module

[dtomaszewski]

Hi,

It's very often use case for global tools like WebAnalytics to create abstraction layer in app to do not stick to one solution. I try to do the same with Matomo module but I find it a bit cumbersome with current version. Issues I see is :

1. There is no way of providing configured abstract module which will internally use MatomoModule. My implementation was about to create WebAnalyticsModule.forRoot(config) with internally configuration of MatomoModule. What I tried was to provide MATOMO_CONFIGURATION separately and import MatomoModule only internally. The problem is that when I want to import my WebAnalyticsService which is facade for MatomoTracker to lazy loaded module I have to import WebAnalyticsModule again but it'll not work because MATOMO_CONFIGURATION has to be provided again otherwise I can't import MatomoModule again (it'll run init() method which needs MATOMO_CONFIGURATION). Solution would be to provide forRoot and forChild methods to MatomoModule

2. When I want to create WebAnalyticsService facade for MatomoTracker it can't be imported to services providedIn: 'root' because MatomoTracker is provided in module only (and needs MATOMO_CONFIGURATION). IMO it should be separate root service independent of MATOMO_CONFIGURATION, otherwise we need store support just to call tracker event in 'root' service.
