testing: Run in parallel mode by default.

Browse Source 
This commit changes the backend testing framework to run
in parallel mode which is same as --processes=4. If --coverage
is supplied, we enforce serial mode, --processes=1, because
coverage is not compatible with parallel mode at the moment.

## Running tests
Our tests live in `zerver/tests/`. You can run them with
`./tools/test-backend`. It generally takes about a minute to run
the entire test suite. When you are in iterative mode, you
can run individual tests or individual modules, following the
dotted.test.name convention below:
`./tools/test-backend`. The tests run in parallel using multiple
threads in your development environment, and can finish in under 30s
on a fast machine. When you are in iterative mode, you can run
individual tests or individual modules, following the dotted.test.name
convention below:
cd /srv/zulip
./tools/test-backend zerver.tests.test_queue_worker.WorkerTest
