Create swarming load test.

swarming_load_test_bot.py creates fake Swarming bots that fake running tasks.
swarming_load_test_client.py creates fake Swarming tasks and wait for them to
complete.
The goal here is to see how the server melts down, if it does, when a lot of
concurrent pending tasks occur.
