Community Pool Staking Rewards Implementation & Improvements (#1742)
* add new field upgrade_time_set_staking_rewards_per_second with intention
of integrating into the disable inflation logic to set an initial
staking reward time

* when the disable inflation upgrade time occurs, set the staking rewards
per second to the value specified by the new
upgrade_time_set_staking_rewards_per_second.  This will allow a decoupled
implementation between the ugprade switching logic, and the core
functionality of paying staking rewards from the pool

* add staking rewards state to community keeper and community module
genesis that is required to calculate and track staking reward payouts
accross blocks

* add implementation of staking reward payouts

* remove unused error

* touch up tests and add a test case that fully tests behavior when pool
is drained

* add function comments

* refactor and pull out main calculation to private pure function with
no dependence on keeper

* zero out default parameters -- these are too chain specific to have
useful defaults

* small touch ups on comments, test cases

* use correct Int from sdkmath, not old sdk types; update protonet genesis
for new parmater

* fix copy pasta comment

* use bond denom from staking keeper instead of referncing ukava directly

* add staking reward state for valid genesis

* update kvtool genesis for new params and rewards state
