Subject: 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
