Subject: [PATCH] TT#40459 Move the rtpengine NFS mount point into its own
 sysvinit script

We detangle the two actions so that they can be performed independently
and on different conditions. This makes it possible to start the
rtpengine-recording-daemon only on the active node, and on some
role-specific nodes, while mounting the NFS filesystem in other
nodes.

We do not remove the nfs-setup start from the recording daemon init
script as sysvinit does not honor dependencies during direct init.d
or service(8) invocations.

[gjover@sipwise.com: Adapt changes to sysvinit. ]

(cherry picked from commit 0224a491621fa0efc71b3cafff2028805cada47d)
