bug fixes for swift 1033089
Swift 1.6.0 All in One setup uses rc.local to create a set of
directories like the following:
/var/cache/swift /var/cache/swift2 /var/cache/swift3
/var/cache/swift4
/var/run/swift
without -p for mkdir command, when some of these directories
already exist, the rc.local fails so that the next set of
command won't execute. This causes swift fail to start because
of /var/run/swift does not exist. Adding -p to both mkdir
command solves this problem.
