Allow to use environment variable from node inventory in directive rudder variables

Web - Config management
Description
In a directive, we are allowed to use rudder parametrized variable, see: http://www.rudder-project.org/foswiki/Development/ContextedVariables
We want to be able to access environment variable value from the node inventory as such variable, with the following semantic:
${rudder.node.env.SOME_VARIABLE} is replaced by:
- "" is the variable does not exist or is empty
- the value of SOME_VARIABLE, considered as a string, as reported in the inventory in the <VAL> tag for the <KEY>SOME_VARIABLE</KEY> tag of an <ENVS>.
For posterity: this ticket was implemented and removed during 3.0 cycle in favor of #5449. A more generic solution will be implemented in #3112
- Pull Request set to https://github.com/Normation/rudder/pull/572
- Status changed from In progress to 10
The tests show that the performances are very lightly impacted by that addition, also meaning that adding any other inventory information is mostly free.
Functionnal review agreed on the following points:
- syntax: ${rudder.node.env.ENVIRONMENT_VARIABLE_NAME},
- replaced by the value of the environment variable "ENVIRONMENT_VARIABLE_NAME",
- case sensitive,
- as known in the last inventory for the node,
- or "" if there is no variable with that name for that node
We now need to add information about allowed parameters in the directive screen, see: #5278

It is to be noted that that feature does not impact the NodeConfigurationCache logic because variable interpolation is done BEFORE the cache check.
