Add ability to show holidays in calendar view.

[amoraitis]

Is your feature request related to a problem? Please describe.
The user will have the ability to import holidays as tasks to the monthly calendar view.

Describe the solution you'd like
Add a new Model class under TodoList/TodoList.Core/Models/:
This will need a new migration for the new UserPreferences table.

class UserPreferences
// In iso-3166 format. 1 for now. _In the future create a config value to support multiple countries._
+ UserId: Guid[Key. 1-1 relationship to ApplicationUser.Id]
+ HolidaysInCountry : string

Use Calendarific which offers 1000 free requests/month.

A clear and concise description of any alternative solutions or features you've considered.

Add an HttpClient. Preferably create an IHolidaysCalendarService interface and an implementation of that at HolidaysCalendarService. Investiagate what methods we will need.

Create front-end code that updates the preferences. In the Calendar view or in the user's account menu(add as user preferences tab). This will automatically attach all holidays when navigating to calendar if UserPreferences.HolidaysInCountries is not null in the DB. So, TodosController.Home() Action will also return a list of holidays to be presented. Prepare the View to show the new Data in the same way the existing TODOs do.

• Add new List of countries to options, preferably a .json file under a /.content folder.
  Use the response from this request.
• Add new key-value pair to secrets.json for Calendarific's API key. And base URL to the appsettings.json.
