report locked machines to consumers of run information
We're persistently seeing machines which are locked for old jobs by scheduled suite runs, or occasionally other things. These nodes are hard to identify: nothing in pulpito or the suite emails gives any indication that this is likely, and the only way to identify it is by listing the nodes and checking them. (I have a few console grep lines and things to make this easier, but it's tedious and has to be checked by a person whenever we feel like it.)
This seems like something a computer could do! Summary emails from a run could include a line at the top about how many machines are still locked to the run. Pulpito could check the lock states when it's generating information. Please implement at least one of these so we have a better chance of detecting and dealing with stale locks.
