[do3meli <info@xxxxxxxxxxxxxxxxxx>]

do3meli has proposed merging ~d-info-e/cloud-init:salt-freebsd-patch into cloud-init:master.

Commit message:
make salt minion module working on FreeBSD.

Previously the module was not working under FreeBSD due to a different package name and some different paths. The module can now be better configured via corresponding config variables in the distro classes.

LP: #1721503

Requested reviews:
  cloud-init commiters (cloud-init-dev)

For more details, see:
https://code.launchpad.net/~d-info-e/cloud-init/+git/cloud-init/+merge/340112

the salt minion module was not really usable on FreeBSD so far. I have adjusted/extended the module with some more config variables that can be set based on the distro for better flexibility and compatibility between different distributions. In particular on FreeBSD system paths, package names and service names are different than on other operating systems. This fixes LP: #1721503
