dice-mfg: restore the `liveness` command #204

Closed flihp closed 4 months ago

flihp commented 4 months ago

A while back we implemented a liveness check before each command gets executed largely because I kept wasting time getting confused by failures that a liveness check would have solved. Once this was done the liveness command was redundant and I removed it. I'm looking at facade now and I'm realizing that they used the liveness command. The in-built liveness check doesn't really help in the facade case because the mfg software needs to differentiate between a failure of the liveness check and a failure in the platform identity programming and certification process.

The easiest thing to do is to just restore the liveness command.

this was dropped in favor of just using the ping command in facade
