HTTPS binding without host name whilst also requiring SNI in-descriptively breaks IIS bindings. #4802

Currently when configuring HTTPS binding in an IIS step, you are able to set no value for Host name yet set Server Name Identification to required.

The end result is a non descriptive error which can be difficult to diagnose.

11:01:54   Info     |       SSL Certificate add failed, Error: 87
11:01:54   Info     |       The parameter is incorrect.

Steps to reproduce:

  1. Create Deploy to IIS step and configure with simple site package.
  2. Set HTTPS binding to either a variable which evaluates to nothing, or leave it empty.
  3. Select Required for Server Name Identification.
  4. After deployment trying to view site bindings in IIS will give you the error The parameter is incorrect.

In the IIS UI you can not select SNI without entering a host name. Octopus ignores this and the provided warning is not descriptive.

We should try and provide a more informative warning to help troubleshoot this easier.
