Priority is required in flow config

Priority is required in flow config

-  The Lithium redesign is now correctly requiring that the
priority field be present in the flow being programmed.  The
fact that this was working with the Helium codebase is a bug
there.

-  This will fix 8 failures currently seen in Li-redesign
flow-services CI

-  This also fixes some WARN messages we get in the robot
logs by using the correct namespace "SSHLibrary" in the utils
library
