Tweak EXPLAIN for parallel query to show workers launched.

Tweak EXPLAIN for parallel query to show workers launched. The previous display was sort of confusing, because it didn't distinguish between the number of workers that we planned to launch and the number that actually got launched. This has already confused several people, so display both numbers and label them clearly. Julien Rouhaud, reviewed by me.
