Create haproxy-moonfire-tls-client.conf

Added a folder for config examples.  And added a config example for using HAProxy using IPv6, TLS, and Client Certs.  This also provides for local users without client certs.

+#
+# This is an example file for providing moonfire-nvr TLS connection support using IPv6.
+# Additionally, this example provides client certificate authentication.
+
+# This example will allow users on the same /64 subnet to access moonfire-nvr 
+# without a client certificate.
+#
+# For this to work properly, the server requires a FQDN assigned to the IPv6
+# address for the server certificate.
+#
+# Please replace MYSERVERCERT, MYROOT_CA, MYSUBJECTDNCHECK as apropiate.
+# And ensure rights are proper for accessing the certificaates.
+# 
+# For my usage, I utilize a DDNS service and a Cert/Key management system.
+# 
+# The IPv6 local check depends on the network prefix with a /64.  Replace
+# MYIPv6NetworkSubnet with the local network prefix.
+#
+# This is running on an RPI4/RaspberryPI OS running multiple cameras at a remote site.
+# Source build without Docker.
+# 
+# Note:  I have modified the Systemd unit file to reflect binding to [::1]:8080
+#
+# As with anything else, this may be a starting place.  Improvements are a neccessity for life.
