Gregory Thiemonge c7f4b4a9db Fix certificate directory creation
When calling ./stack.sh twice, octavia devstack plugin fails because
local certificate directory already exists.

This commit deletes the directory each time a certificate creation
script is called and when the user cleans up his devstack's
installation.
