* Move 'stop' services to pre-hook and post-hook. This way they will also be stopped and started when renewing.
- remove service stop/start tasks
- add pre-hook/post-hook templates
- add pre-hook/pos-hook template tasks
- create missing directories at first run
- run pre and post hook during first manual run
- introduces a variable certbot_from_git
- adds install from package tasks
- makes a variable called certbot_script available (to handle certbot vs certbot-auto naming)
- fixes#18
this is a preparation for installing certbot from package management
additionally, it might be useful when further tasks are added, e.g. for initial certificate retrieval
