Infrastructure Alerting manifest doesn't need to set net.ipv4.ip_nonlocal_bind

[Simon Pasquier]

In deployment_scripts/puppet/manifests/nagios.pp

# This is required so Apache and Nagios can bind to the VIP address
exec { 'net.ipv4.ip_nonlocal_bind':
  command => '/sbin/sysctl -w net.ipv4.ip_nonlocal_bind=1',
  unless => '/sbin/sysctl -n net.ipv4.ip_nonlocal_bind | /bin/grep 1',
}

The same command is also executed in the OCF scripts so it's probably useless to have it in the Puppet manifest.
