Change ForceOpen

[GFlisch]

Currently the Force of an OpenId connect is based on a set of string in the appsettings file based on the following pattern:
/xxxx/*
/yyyy

With the * it means everything starting with otherwise compare in a strict way.

I suggest to transform this in a Regex expression and to build this regex when the service is started (singleton) for performance.
This could also then be used for the Csp code....

The current code target is here:

        // if we have some part of the site working like a web page (like swagger, hangfire, etc...) and we need to force
        // authentication. We can add the start of the path to check and in this case we force a login!
        if (context.User is not null && context.User.Identity is not null && context.User.Identity.IsAuthenticated is false)
        {
            if (_options.ForceAuthenticationForPaths.Any(r =>
            {
                return context.Request.Path.HasValue
                       && (r.Last().Equals('*') ?
                            context.Request.Path.Value.StartsWith(r.Remove(r.Length - 1), StringComparison.OrdinalIgnoreCase)
                            :
                             context.Request.Path.Value.Equals(r, StringComparison.OrdinalIgnoreCase));
            }))
            {
                _logger.Technical().LogDebug("Force an OpenId connection.");
                var cleanUri = new Uri(new Uri(context.Request.GetEncodedUrl()).GetLeftPart(UriPartial.Path));
                if (Uri.TryCreate(_options.RedirectUrlForAuthority, UriKind.Absolute, out var authority))
                {
                    cleanUri = new Uri(authority, cleanUri.AbsolutePath);
                }
                var properties = new AuthenticationProperties() { RedirectUri = cleanUri.ToString() };
                await context.ChallengeAsync(OpenIdConnectDefaults.AuthenticationScheme, properties).ConfigureAwait(false);
                return;
            }
        }

    }
    catch (Exception ex)
    {
        _logger.Technical().LogException(ex);
    }
