allow neutron::agents::ovs without package install

This alters the service notification and dependency behaviour for
neutron::agents::ovs such that if the package is not installed (i.e.
package_ensure => absent, enabled => false) the class still runs without
producing errors.  This is to allow the generation of config files
without needing to install the package in the first place.

Adding manage_service parameter to all services

When set to false, enables puppet to configure a service without
starting/stopping it on each run.  This may be necessary when
using an external clustering system (Corosync/Pacemaker, for
example).  Defaults to true.

Fix to remove conflicted symlink

Since cisco plugin coexists with ovs, a symlink
pointing to ovs already exists causing a conflict
with cisco_plugins.ini. This fix should default
the symlink to ovs.
