Bug 1683525 - set CRLite back to telemetry-only mode r=kjacobs

This is a backout of b635c277c9f4 (bug 1675138).

It seems that the CRLite certificate transparency ingestion machinery is
missing certificates it should know about, which means that false positives are
possible, which means that users are seeing revoked certificates where they
shouldn't. This patch sets CRLite back to telemetry-only mode while the
infrastructure gets fixed.
