Add Loadblancer feature

[rgroux]

Metallb can be nice to add the awesome LB services to the kubernetes cluster when it s a metal on, not an aws/google/azure.

i test and use it since a week, it work like a charm, i will make a ne PR for this after check how to enable it into the post_install service if you think it can be nice.

it will be a very short and simple PR, there are only 1 input parameter, the External IP range.

Hi @rgroux,
It's really a great idea, and why not make it enableable from the pillar.
I looking forward for the PR ;)
