wait and retry method pattern

example.cs

WaitAndRetry.Do(MethodThatCanFail(), TimeSpan.FromSeconds(1));
WaitAndRetry.Do(MethodThatCanFail(), TimeSpan.FromSeconds(1), 5);

AppJobResult result = WaitAndRetry.Do(() => MethodThatCanFail(), TimeSpan.FromSeconds(1));
AppJobResult result = WaitAndRetry.Do(() => MethodThatCanFail(), TimeSpan.FromSeconds(1), 5);
