Subject: waiverdb: Set fixed number of processes ans threads


New waiverdb container image starts 8 gunicorn web worker processes by
default using WEB_CONCURRENCY environment variable. This causes memory
to spike (over 500MiB) and workers to get terminated.

Instead of increasing memory limits, a better solution is to decrease
the number of processes and increase number of threads since the app
mostly waits on DB requests to finish and waiverdb workers themselves
are thread-safe.
