ajoute le stock chaud, la correction automatique et les nouveaux essais de création de stack

Browse source 
Stock de stacks prêtes par lab dans Redis (prise atomique en Lua, ménage
par comparaison avec Heat, disjoncteur), files gérées par Horizon, séances
planifiables. Correcteur Go sur l'hyperviseur : socket Unix, commandes lues
dans le lab.yaml uniquement, exécution par l'agent invité QEMU. Une création
de stack ratée est supprimée et réessayée deux fois, puis la session passe
en échec, visible du prof.

Corrige aussi trois défauts des étapes précédentes : la console se coupait
à la première frappe d'un navigateur (trames texte), l'élève ne pouvait pas
rejoindre une séance, la déconnexion n'avait pas de jeton CSRF.
