Pull mode for remote execution in Satellite will stop working

Please provide the package NVR for which the bug is seen:

yggdrasil-0.4.6

How reproducible is this bug?:

Always

Steps to reproduce

1) Have yggdrasil < 0.4.6
2) Configure it to connect to a mqtt broker without explicitly setting `protocol` option to `mqtt`
3) Update yggdrasil to 0.4.6

Expected results

Yggdrasil continues to connect to the broker

Actual results

Yggdrasil does not connect to the broker, because the default value for protocol option changed to `none` in 0.4.6.
