no way to tell from spread log output which tasks _succeeded_

[anonymouse64]

Spread makes it very obvious what things failed:

2020-10-26T19:30:59.1053887Z error: unsuccessful run
2020-10-26T19:30:59.1055189Z 2020-10-26 19:30:59 Successful tasks: 5

But it does not make it clear from the log or from the end output what passed. I don't think it needs to list out all of the passing tests at the end, as in most cases this will just be noise, but when run with -v I think spread should indicate something in the log that can be grepped for to tell that a test passed, for example from the above run we had:

(with lots of other tests interspersed in the actual output, the above was filtered for just lines related to the test google-nested:ubuntu-20.04-64:tests/nested/classic/hotplug)

it would be nice if after a test passed it had something like

2020-10-26T18:11:51.7524676Z 2020-10-26 18:11:51 Preparing google-nested:ubuntu-20.04-64:tests/nested/classic/hotplug (oct261801-050775)...

or the Success executing line could even be combined with Restoring to be something like:

Basically something that makes it easy to grep a verbose log to tell:

• If a specific test I care about passed
• What the set of tests that passed was

Again, this doesn't need to be in the default output, the verbose output is enough for our use cases I think.
