Configure different Docker volume sizes for different roles (#644)
* README, all.yml, stack_params.yaml, openstack-stack: added docker volume size customisation - app_volume_size changed to node_volume_size (it is node everywhere else) * all.yml, stack_params.yaml,openstack-stack: added customisation for lb, etcd, dns * README: updated * README: updated info about ephemeral volumes

The `openstack_nodes_to_remove` allows you to specify the numerical indexes
of App nodes that should be removed; for example, ['0', '2'],
+The `docker_volume_size` is the default Docker volume size the servers will use.
+In order to set a different volume size for a role,
+uncomment the line with the corresponding variable (e. g. `docker_master_volume_size`
+for master) and change its value. `docker_volume_size` must stay defined as it is
+used as a default value for some of the servers (master, infra, app node).
+The rest of the roles (etcd, load balancer, dns) have their defaults hard-coded.

+**Note**: If the `ephemeral_volumes` is set to `true`, the `*_volume_size` variables
+will be ignored and the deployment will not create any cinder volumes.

The `openstack_flat_secgrp`, controls Neutron security groups creation for Heat
stacks. Set it to true, if you experience issues with sec group rules
quotas. It trades security for number of rules, by sharing the same set
