feat(api): add GET routes that mirror POST routes in express

[daywiss]

Motivation

we want to add some kind of health check to the bots to make sure our connection to datastore is working. this can be done as long as we have a way to query routes through "GET". currently these actions require a POST.

Summary This does not break any existing functionality, only mirrorss the POST calls to GET calls using the exact same underlying logic

for health checks, you can now hit GET global/listActive

UMA-1912 Still seeing uma api listActive errors

That way GCP could send this health check and auto restart the instance whenever that call fails.
