Can't use device from grid without STF-agent connected

[azarouski]

I have following workaround:

1. Device connected to server
2. Appium instance connected to device and successfully registered in mcloud/grid/console
3. No mcloud-device container started

docker run -itd --name device-Samsung_Galaxy_S7-123123123123-appium -m 1g --log-opt max-size=1024m --log-opt max-file=2 --net=infra \
--restart on-failure \
--link device-Samsung_Galaxy_S7-123123123123-connector:connector \
-v appium-storage-volume:/opt/appium-storage \

When i'm trying to run tests on this device i have following error logs in mcloud-grid:2.5 container

these logs are produced by the following code

When i'm starting mcloud-device(STF) container everything works fine.

Let's discuss how to fix this problem and should we fix it.
