Configuration readability improvement, fix Vagrantfile and fix service watch

[amontalban]

Hey guys,

This PR address the following things:

1. Improve configuration readability, before this PR with the pillar.example the configuration looked like:

# -*- coding: utf-8 -*-
# vim: ft=jinja
    
    
check process nginx with pidfile /var/run/nginx.pid
    
    
    
  group www
  start program = "/etc/init.d/nginx start"
  stop program = "/etc/init.d/nginx stop"
  if failed host 127.0.0.1 port 80 protocol http then restart
  
check process postfix with pidfile /var/spool/postfix/pid/master.pid
    
    
    
  group mail
  start program = "/etc/init.d/postfix start"
  stop program = "/etc/init.d/postfix stop"
  if failed port 25 protocol smtp then restart
  
check process cron with pidfile /var/run/cron.pid
    
    
  group system
  start program = "/etc/init.d/cron start"
  stop program = "/etc/init.d/cron stop"
  depends on cron_rc
  
    
    
check file cron_rc with path /etc/init.d/cron
    
    
    
    
    
  if failed checksum then unmonitor
  if failed permission 755 then unmonitor
  if failed uid root then unmonitor
  if failed gid root then unmonitor
  
check process gdm with pidfile /var/run/gdm.pid
    
    
  start program = "/etc/init.d/gdm start"
  stop program = "/etc/init.d/gdm stop"
  

Now it looks like:

# -*- coding: utf-8 -*-
# vim: ft=jinja
    
check process nginx with pidfile /var/run/nginx.pid
  group www
  start program = "/etc/init.d/nginx start"
  stop program = "/etc/init.d/nginx stop"
  if failed
    host 127.0.0.1 port 80 protocol http
  then restart
  
check process postfix with pidfile /var/spool/postfix/pid/master.pid
  group mail
  start program = "/etc/init.d/postfix start"
  stop program = "/etc/init.d/postfix stop"
  if failed
    port 25 protocol smtp
  then restart
  
check process cron with pidfile /var/run/cron.pid
  group system
  start program = "/etc/init.d/cron start"
  stop program = "/etc/init.d/cron stop"
  depends on cron_rc
  
    
check file cron_rc with path /etc/init.d/cron
  if failed
    checksum
  then unmonitor
  if failed
    permission 755
  then unmonitor
  if failed
    uid root
  then unmonitor
  if failed
    gid root
  then unmonitor
  
check process gdm with pidfile /var/run/gdm.pid
  start program = "/etc/init.d/gdm start"
  stop program = "/etc/init.d/gdm stop"

2. Fix Vagrantfile to work and also allow to change pillar.example in the host and have it available in the VM. Additionally I used linked_clone to improve tear down/creation times.

3. When the pillar don't include mail_alert setting the service failed to start due to the watch statement, so I did the other way around by using watch_in.

4. Add support for FreeBSD.

5. Allow to change other Monit settings like daemon interval or syslog. Also instead of passing the context to template files I import the map directly.

6. Allow to configure the service status (In my use case I need the service to be enabled but not running).

Thanks!
