Actions CLI - tracer implementation

Just connects the command line 'actions' and 'do' to the apiserver; basic initial CLI implementation
ISTM that there's already a saner type trying to get out? Something like ActionStatus{Tag,Uuid,Status} as a result for both the creation of actions and the `action list` level of output?

(and then ofc, because bulk:
    type ActionStatus struct{}
    type ActionStatusResult struct {
        Result *ActionStatus
        Error *Error
    }
    type ActionStatusResults struct {
        Results []ActionStatusResult
    }
)
