## Description
Get state of invoker container pool over http route.
New GET route `/pool` returns a high level overview of the current state of
its container pool. Useful for numerous things, one is being able to know when
a disabled invoker has cleared out so it can be gracefully clear out. But also
useful just for seeing a live state of things. We can leave it an experimental
api for now subject to change.
Here is an example output:
```
{
"busyPool": {
"containers": [
{
"action": "test_action",
"containerId":
"1f485e8dbda91997e8e16b26c2e025b0cd453c9cc10a4cc678dd427abc614301",
