Main states kind segregation

Overview

In makina states we have organised our states in the following way:

controllers:states related to the base salt infrastructure (layout, deamons, permissions) nodetypes:states related only to the hardware, the machine type or virtualisation facillity localsettings:states related to the base machine configuration minus all that can looks like a service or a deamon (eg: directories creations, hosts managment, pam, vim but not ssh) services:states related to services configuration (eg: ssh, docker, apache, backups scripts & crons) projects:Set of macros to be externallly included project consumers as the base to setup their projects using makina-states bricks cloud:set of related stuff linked to mastersalt salt cloud integration

For all those kinds, we have execution modules, sub-execution modules and formulaes containers. to leverage and factorize all variables and have well placed macros.

For exemple, php users will certainly have to deal the following files:

mc_states/modules/services.py:  registries mc_states/services/{http,php}/*.sls:  states files (formulaes) /srv/pillar/foo.sls:  custom settings
