Alex Vandiver feb7870db7 puppet: Adjust thresholds on autovac_freeze.
These thresholds are in relationship to the
`autovacuum_freeze_max_age`, *not* the XID wraparound, which happens
at 2^31-1.  As such, it is *perfectly normal* that they hit 100%, and
then autovacuum kicks in and brings it back down.  The unusual
condition is that PostgreSQL pushes past the point where an autovacuum
would be triggered -- therein lies the XID wraparound danger.

With the `autovacuum_freeze_max_age` set to 2000000000 in
`postgresql.conf`, XID wraparound happens at 107.3%.  Set the warning
and error thresholds to below this, but above 100% so this does not
trigger constantly.
