Agent level Security (api everywhere)

Registered by Antonio Rosales on 2013-04-21

[GOAL]
Restrict possible impact of compromised units/machines

[RATIONALE]
By ensuring that most machines and units in an environment are located separately from the state server, and use credentials that only allow a minimal necessary subset of operations via the API, we can limit the impact of security failures and bugs on those machines by ensuring that they cannot accidentally or maliciously corrupt state directly, and cannot access information (such as the user's environment credentials) that would enable escalation beyond that implicitly made possible via the relation unit settings available to a compromised unit.
