Rework instance actions to work with cells

In a cells setup an instance action is recorded at the global cell level
while events try to get recorded in a child cell compute node or
scheduler.  The event recording fails because it can't find an action to
link to.  This patch adds the recording of actions at the child cell
level, and changes the API extension to query the db in a child cell for
the record of actions and events.

This does not address the fact that an action is recorded at the global
cell level.
