Tkach/refactor email sender

[jimmy2jk]

Sumary of issue

EmailSenderJob had a dependancy on SendGridClient and so in dev environment emails could not be logged to debug console.

Summary of change

Added IEmailSender interface and two implementations:

• DevelopmentEmailSender: sender for dev env that simply logs email to debug console;
• SendGridEmailSender: sender that depends on SendGridClient and actually sends emails in NOT dev env.

EmailSenderJob now depends on IEmailSender instead of SendGridClient. Delete DevEmailSender as it's responsibility now implemented by DevelopmentEmailSender. Registration of appropriate email sender is based on environment. Split registration of EmailSenderService and EmailSenders into different extension methods. Adjust existing unit tests to work correctly with made changes and cover new senders with unit tests.
