[Bug] Remove ForceHttpsRedirectUris

[Tratcher]

https://github.com/AzureAD/microsoft-identity-web/pull/202/files#diff-f39916663b976a444b0a47747df21822R62 Added ForceHttpsRedirectUris to work around scenarios where the app is behind a reverse proxy. This is an incomplete workaround for the scenario and should be removed. E.g. other components that depend on the request scheme still do not get the correct value like cookies.

The AspNetCore guidance for working with proxies is here:
https://docs.microsoft.com/en-us/aspnet/core/host-and-deploy/proxy-load-balancer?view=aspnetcore-3.1

• Address the issue centrally by using UseForwardedHeaders to fix up the request fields like scheme.
• Do not add workarounds to individual components.

The container scenario should have been addressed by default in .NET Core 3.0.

MicrosoftIdentityOptions.RedirectUri seems like it's trying to address the same problem and should also be removed.

microsoft-identity-web/src/Microsoft.Identity.Web/MicrosoftIdentityOptions.cs

Lines 31 to 42 in 0e68799

	/// <summary>
	/// In a web app, gets or sets the RedirectUri (URI where the token will be sent back by
	/// Azure Active Directory or Azure Active Directory B2C).
	/// This property is exclusive with <see cref="RemoteAuthenticationOptions.CallbackPath"/> which should be used preferably if you don't want
	/// to have a different deployed configuration from your developer configuration.
	/// There are cases where RedirectUri is needed, for instance when you use a reverse proxy that transforms HTTPS
	/// URLs (external world) to HTTP URLs (inside the protected area). This can also be useful for web apps running
	/// in containers (for the same reasons).
	/// If you don't specify the redirect URI, the redirect URI will be computed from the URL on which the app is
	/// deployed and the CallbackPath.
	/// </summary>
	public string RedirectUri { get; set; }

Oh, and MicrosoftIdentityOptions.PostLogoutRedirectUri

microsoft-identity-web/src/Microsoft.Identity.Web/MicrosoftIdentityOptions.cs

Lines 44 to 53 in 57184a3

	/// <summary>
	/// In a web app, gets or sets the PostLogoutRedirectUri.
	/// This property is exclusive with <see cref="OpenIdConnectOptions.SignedOutCallbackPath"/> which should be used preferably if you don't want
	/// to have a different deployed configuration from your developer configuration.
	/// There are cases where PostLogoutRedirectUri is needed, for instance when you use a reverse proxy that transforms HTTPS
	/// URLs (external world) to HTTP URLs (inside the protected area). This can also be useful for web apps running
	/// in containers (for the same reasons).
	/// If you don't specify the PostLogoutRedirectUri, it will be computed by ASP.NET Core using the SignedOutCallbackPath.
	/// </summary>
	public string PostLogoutRedirectUri { get; set; }
