Avoid killing instances upon scale down when it is unnecessary (#39)

Example of issue that is fixed with this patch:
- context: an app has 100 green instances and 50 unscheduled ones
- trigger: the app is scaled down to 100 instances
- issue: Marathon deletes 50 green instances instead of the unscheduled ones

v1.9.109-criteo13

Health check shield API

Implementation of an API which temporarly prevents the task from being killed when it's unhealthy.
This is required to support troubleshooting scenarios when the app is "legally" unhealthy, for example when taking a memory dump.

API:
- GET /v2/shield: show current shields
- PUT /v2/shield/<task_id>?ttl=<ttl>: add the shield
- DELETE /v2/shield/<task_id>: remove the shield

Regarding authorization:
- read access (GET) only require authentication
- write access (PUT & DELETE) requires UpdateRunSpec of specified task
If there's no application delete is allowed (to be able to cleanup shields of stale apps using API)

Finally fixed the bug where marathon were not releasing the lock

This was appearing because the KillStreamWatcher was waiting for all
tasks to die, and not only the overdue ones.

This was appearing most of the time when tasks were Unreachable because
they sometimes re-appear while marathon already scheduled new ones.
