Master broken on EL6 due to "Invalid service provider 'sysv'"

[fatmcgav]

When mistakenly using master, I observed that this module was broken on my CentOS 6 test box with the following error:

Invalid service provider 'sysv' at /modules/consul/manifests/run_service.pp:19

A quick browse through the code suggests that 85de0cd is the cause of this breakage, specifically whereby it's enforcing the provider param.
On <EL7, the default provider is init, not sysv.

Running through the history on params.pp, it looks like the this was first entered into params.pp in 24931c8, however as it was never passed through the service, it was never an issue previously...

PR incoming to correct default value on <EL7...

Cheers
