ACE/ACI shutdown guidelines?

[krobertson]

Was reviewing the teardown handling in kurma and was wondering if some guidelines should be added around signals to shutdown apps/pods.

A reasonable guideline would likely be the Kubernetes definition of a TERM, followed by a grace period, and a KILL if the period expires.

Seems reasonable - wanna put up a PR?
/cc @alban @iaguis for rkt/systemd impl.

[krobertson]

Will do.
