ICP-10136 - Zooz Power Strip: calling sendHubCommand() once with all …

…commands (for all endpoints) (SmartThingsCommunity#11431) (SmartThingsCommunity#11483)

* ICP-10136 - calling sendHubCommand() once with all commands (for all endpoints)

* ICP-10136 - decreased delay between commands send from refresh() to 200 milliseconds
