Log that master is connected and for which test_result this run is

Also log if master told us that we have nothing to do, and if the mode to run is local.

This should make it a bit more clear what is going on just by looking at
nxdtest log. See previous patch for more details and context.

For the reference: here is how updated output looks like in the normal case:
