Added docker-compose bash completion (I think it was there but it's gone missing).

.bash_completion.d/docker-compose

+#!/bin/bash
+#
+# bash completion for docker-compose
+#
+# This work is based on the completion for the docker command.
+#
+# This script provides completion of:
+#  - commands and their options
+#  - service names
+#  - filepaths
+#
+# To enable the completions either:
+#  - place this file in /etc/bash_completion.d
+#  or
+#  - copy this file to e.g. ~/.docker-compose-completion.sh and add the line
+#    below to your .bashrc after bash completion features are loaded
+#    . ~/.docker-compose-completion.sh
