activation poll

[starpit]

origin: kubernetes-sigs/kui#2398

A common set of commands when developing is:

1. activation list
2. click an activation (activation get)
3. do some out of band activation which causes new activations
4. go to 1

What if there was an activation poll instead (which the wsk cli offers) which continuously updates the activation list view with new activations, with support for specific action names to keep the focus on activations of interest.

It would avoid steps 1 and 4 above because a developer could iterate between do stuff and click new activation.

A possible nuance is the rate of the poll and ingesting too many activations at once... perhaps a slider or command line argument could control the rate.
