consensus: adjust bip9 periods

10x the default counting periods.
Previous period was 2016 blocks or about 1.4 day.
Proposed period is 20160 blocks or about 14 days.

- The LOCKED_IN period is extended from 1.4 to 14 days, during which non upgraded nodes will be warned of the upcoming fork.
- 10 times as expensive to potentially try to force activation with rented hashpower.
- Slower activation. Previous minimum activation time from counting starts, about 3 days, with this proposal about 30 days.
