1. Add to AdminProfileEntity
   [Column("email_verified")]
   public bool IsEmailVerified { get; set; }
2. Add EF migration that adds this property to AdminProfileEntity
3. Add to Lykke.Service.CustomerProfile.Domain.Models.AdminProfile and to Lykke.Service.CustomerProfile.Client.Models.Responses.AdminProfile
   public bool IsEmailVerified { get; set; }
4. Subscribe to AdminEmailVeridfied event from MAVN.Service.AdminManagement.Contract (Define AdminEmailVeridfied in Contract project MAVN.Service.AdminManagement#9) in AdminEmailVerifiedSubscriber (similar to https://github.com/OpenMAVN/MAVN.Service.CustomerProfile/blob/master/src/MAVN.Service.CustomerProfile.DomainServices/Subscribers/CodeVerifiedSubscriber.cs).
