memory plugin template doesn't work with newer collectd versions

[alexlist]

Affected Puppet, Ruby, OS and module versions/distributions

• Puppet: 3.6.2
• Ruby: 2.0.0p648
• Distribution: RHEL 7.3
• Module version: 4.2.0

How to reproduce (e.g Puppet code you use)

https://github.com/voxpupuli/puppet-collectd/blob/master/templates/plugin/memory.conf.erb contains an if clause that tests for collectd 5.5, however on RHEL7 I have 5.7. The test seems to be wrong, or should check for versions greater or equal than 5.5, but not just 5.5

What are you seeing

Setting valuespercentage => true does not have any effect

What behaviour did you expect instead

A collectd memory plugin config stanza enabling percentage values
