Resync every 10h instead of every 30s

[imjasonh]

Fixes #541

Proposed Changes

• Resync our custom resources every 10 hours, and rely on build/pod watch updates to trigger syncs in most cases

Resyncing every 30s seems to lead us to hit rate limits that we never recover from when there are too many builds in the system at a given time. Serving also switched to resyncing every 10h for similar scaling reasons.

Release Note

NONE
