Plugin sockets cannot be more than 108 characters long #4
Description
Therefore with boot2docker we're being forced to name the directory /mnt/sda1/var/lib/<containerid>/p/p.s which is gross.
If we used plugin names derived from the image name and put the socket files in e.g. /var/lib/docker/plugins/clusterhq.flocker/plugins/. this would workaround this limitation, allowing us to use more meaningful directory and socket names.
