Set the CDP Block Interval to 100 during v0.26.x upgrade (#1865)

Browse Source 
* set CDP block interval to 100 to only run interest synchronization
for risky cdps every 100 blocks instead of every block

* refactor and use constant for setting to improve clarity; update
block interval to 50 instead of 100.  This will decrease risk by
running around every 6 minutes instead of 12 mintues for current
mainnet block times.
