DB_POOL default value weirdness

[bglusman]

It's friday and just had a weird bug in our new kubernetes infrastructure want to capture here because it doesn't make sense to me... but in rails console, database connections were working fine, but in toiler, we were getting 100% only database connection timeouts... normally DB_POOL defaults to 5 in rails if no value set, but somehow in Toiler, without this set it was... I dunno, defaulting to 0 or something... does that make any sense to you @sschepens ? May investigate next week, but seems weird. Also FYI to @gtaschuk to discuss/look into together next week.
