Introduce node and group level vars
Variables can now be fed to model from multiple locations. In order of preference: 1) node (from source) 2) group 3) global In a model vars should be accessed via 'vars' helper method though it is not required. Helper method ignores nil values so care needs to taken when designing model behaviour. Support for node level vars is currently available on sql source via 'vars_map' configuration. Following example populates node vars 'enable' and 'somevariable' from sql columns 'var_enable' and 'var_somevariable' sql: adapter: sqlite file: /home/aakso/.config/oxidized/sqrouter.db table: nodes map: name: hostname model: model group: node_group username: username password: password vars_map: enable: var_enablepw somevariable: var_somevariable
