Unused line of code, remove or update readme

[samos123]

The following line seems no longer being used?

{%- set if = grains['maintain_hostsfile_interface'] %}

If it's still in use we should update readme, if it's not in use anymore maybe we can remove it. also setting a variable name to be if is really confusing as if can also be an if statement.

Oh dear .... if as variable name is really quite suboptimal and I see no reason why we wouldn't want to remove that line as it is no longer used.

Ok pull request incoming, i thought it was maybe some jinja magic I didn't understood haha.
