描述
There are use cases when building custom Identifiers to create some sort of initial state (create connections to db, etc) It would be nice to have linkerd lifecycle status propagated to the identifiers, so they can do the creation and release of resources efficiently
I am thinking something like
trait LinkerdLifecycle {
def onStart() = {}
def onStop() = {}
}
that Identifiers can build on top of it.
