Elect primary / failover policies
Adds an `ElectPrimaryPolicy` and related items to facilitate contexts which
want a primary node, with failover/reelection, and ability to propagate sensors
from primary, specify preferences, and invoke methods on promote/demote.
Depends on (and includes) #878 which adds some minor enhancements elsewhere.
See docs PR to follow for example and more explanation.
