rhel: Add OVSREQUIRES to automatically bring up OpenFlow interface dependencies
The use of OpenFlow controllers may require for a subset of
the network (typically the management network intrerface) to be
brought up before the openvswitch service is started.
The newly introduced key "OVSREQUIRES" allows to specify a
list of interfaces that need the be brought up before the
openvswitch service is autostarted. It is also possible to
build a chain of bridge dependencies.
TYPE=OVSBridge
OVSREQURIES="em1"
[...]
A special UPPEDSTACK var that is passed along avoids getting
lost in dependency loops.
