Linker removes all setters for CertificateConfig in Kestrel

[benaadams]

Compile ASP.NET Core app with ASP.NET Core linking on an all the setters for CertificateConfig are removed; which means a "Certificates" section in config cannot be loaded and Kestrel will therefore ignore all the settings

aspnetcore/src/Servers/Kestrel/Core/src/Internal/ConfigurationReader.cs

Lines 369 to 385 in 292cb9c

	public string Path { get; set; }
	public string KeyPath { get; set; }
	public string Password { get; set; }
	// Cert store
	public bool IsStoreCert => !string.IsNullOrEmpty(Subject);
	public string Subject { get; set; }
	public string Store { get; set; }
	public string Location { get; set; }
	public bool? AllowInvalid { get; set; }

It entirely binds the type via reflection + config via ConfigSection.Bind(this) so no properties setters are specifically referenced; which is presumably why the linker doesn't keep them?

aspnetcore/src/Servers/Kestrel/Core/src/Internal/ConfigurationReader.cs

Lines 353 to 357 in 292cb9c

	public CertificateConfig(IConfigurationSection configSection)
	{
	ConfigSection = configSection;
	ConfigSection.Bind(this);
	}

If it was changed to manually bind the properties as per ReadEndpoints() and ReadSni() and ReadEndpointDefaults() in the same file the linker would presumably then keep the setters?
