Default value of keepalived::vrrp::script::weight is different from keepalived's default

[ftsamis]

The puppet module has a default value of 2 for keepalived::vrrp::script::weight. While the default for this option in keepalived itself is 0 according to https://github.com/acassen/keepalived/blob/master/doc/keepalived.conf.SYNOPSIS which states:

The default weight equals 0, which means that any VRRP instance monitoring the script will transition to the fault state after <fall> consecutive failures of the script.

This misalignment probably occurred due to acassen/keepalived#484
