Change config function providers to be mutable
Also change logsChannelSecret value to be queried with the api backend, so that logs are not shared between instances. This has been implemented as the first config function provider with mutability. Change-type: minor Closes: #675 Signed-off-by: Cameron Diver <cameron@resin.io>
