Campaign Managers can view list of Managed Campaigns

[stevejgordon]

Breakout from #1802

Update campaign lister if possible or add a new lister page where a campaign manager can see links to all campaign(s) they have access to manage.

Clicking the link should take them to the admin campaign page.

@stevejgordon Working on it, what campaign manager has access to is determined by the values in CampaignManager table, am I right?

[stevejgordon]

@HamidMosalla Yes that's correct. That table maps users to campaigns they are allowed to manage.

@stevejgordon I need to decide on how to implement the security aspect of this, what I chose is to create a method in claim extensions something like:
public static bool IsCampaignManager(this ClaimsPrincipal user)
Am I going the right path? If so, it mean adding a new UserType and new claim, which makes the campaign manager a special user, or I could get the current user's id and check to see if it exist in the CampaignManager table, which will show the manage campaign page to every user, I'm not sure.

@HamidMosalla We have some authorization concepts now that partially enable this. I've just checked and I have some code I started to update a new UserAuthorizationService that I added a few weeks ago. This service get's hooked up by middleware and will become our single point for user authorization code.

I'll see if I can finish that off this morning and get it checked in, since that will then give you an IsCampaignManager bool on this service.

@HamidMosalla - I've submitted PR #1990 to add helper methods to expose the current user's authorized access types.

@stevejgordon It's done, thanks for the quick response regarding the authorization, let me know if there was any problem.
