We recently began altering the mount map used by the wrapper driver for each execution run (so that we can only include the current playbook). However, the setMountsMap method operates on the global driver object rather than an object more closely bound to the lifetime of the playbook run. The fact that this works at all is just luck (executing process is slow enough that hitting a race condition where the wrong directories are mounted is unlikely). To correct this, add a new layer which contains the context for the current playbook execution. Change-Id: I3a06f19e88435a49c7b9aea4e1221b812f5a43d0
