Add host mount compatible Complement image

build/scripts/ComplementLocal.Dockerfile
+# A local development Complement dockerfile, to be used with host mounts
+# /cache -> Contains the entire dendrite code at Dockerfile build time. Builds binaries but only keeps the generate-* ones. Pre-compilation saves time.
+# /dendrite -> Host-mounted sources
+# /runtime -> Binaries and config go here and are run at runtime
+# At runtime, dendrite is built from /dendrite and run in /runtime.
+#
