[arthur91f]

Permit to return where are the implementation problem of exeIaC
brick.yml that haven't a good format...

Error to return:

• check brick.EnrichError
• check circular deps (brick.Inputs reference a brick with a following index)
• check 2 brick_path don't have the same brick_name ? (is it necessary)
• check module.LoadAvailableActions() for each module (think to also check local module)

Info to return:

• check all module
• calculate the possible layer of a brick and display the useless layer (BONUS, if it's too long or complicate create an other ticket in backlog for that)
