Allow to deploy dual-master with existing EFS

Currently the creation of a dual-master stack always creates a new,
empty EFS filesystem. Whilst this is good for the first deployment of a
stack, it is not suited for deploying a stack leveraging existing data.

Being able to specify an EFS stack (together with the ability of
specifying an existing EBS snapshot), allows to recover stacks from a
specific point in time, as well as performing a blue/green deployment in
which the two co-existing stacks point to the same data.
