Reduce flakiness of e2e tests caused by write contention in sqlite
Write contention in sqlite on startup intermittently causes failed tests because
of failed service runs. This can have various root causes, one example is
dashboard provisioning:
Dashboard provisioning's frequent commits can cause other read transaction
snapshots to invalidate and throw SQLITE_BUSY/SQLITE_BUSY_SNAPSHOT. If those
failing transactions have a long length but not long enough to ensure all of
the dashboards have finished provisioning it will run out of retries and fail
entirely.
This change helps indirectly reduce these write contentions by limiting the
connection pool for e2e tests.
As a bonus, having our e2e tests run using `max_open_conn = 2` means it acts
as a guard against regressions that would affect certain internal instances
that run with these settings.
