feat(community): add switchover param (#1704)

* add community params type * add get/set params methods * add community genesis state type * add community init/export genesis * add querier methods for params * add query cli cmd * update changelog * update protonet genesis * Add `RewardsPerSecond` param to `x/community` module (#1707) * Add RewardsPerSecond param to community * Update rewards per second param to int * Add rewards_per_second to protonet genesis * Use default rewards per second of 744191 * Include value if negative in Validate error * Rename RewardsPerSecond param to StakingRewardsPerSecond * Add changelog entry * Add param migration, update consensus version to 2 * Update proto docs * Update staking_rewards_per_second param name in protonet genesis (#1730) * Update godoc Co-authored-by: Robert Pirtle <Astropirtle@gmail.com> * add genesis state tests * document what 0 upgrade time means * update kvtool to include new params --------- Co-authored-by: drklee3 <derrick@dlee.dev> Co-authored-by: Robert Pirtle <Astropirtle@gmail.com>
