Eventemitter and Observable for functionality

[Gnyblast]

I realized that for google analytics to work and that kind of anything, you need to inform sometimes some 3rd party APIs about what are the selections of the end user from the cookie consent. In order to achieve that I implemented some event emitters and observable into the code that you can either lister the event or subscripbe the service observable and take action depending on what you want to do.

• Adding Eventemitter to the template and component ts file
• Adding observable for functional or marketing cookies for cookie-consent service for subscription

My lintering settings are did some ; refactorings by default, you can remove them if you don't like.

I found out that your cookie-manager.service exposing these functionalities on an observable which satisfies this need.
