ADD: Churn Epochs on /constants
Current
Deep in the TC code is this line: https://gitlab.com/thorchain/thornode/-/blob/v1.97.2/x/thorchain/manager_network_current.go#L316
amt = amt.MulUint64(uint64(nth)).QuoUint64(5)
It dictates the number of churn epochs, which is hardcoded to 5.
Desired
Add this to /constants and /mimir
"ChurnEpochs" = 5
//
churnEpochs, err := vm.k.GetMimir(ctx, constants.ChurnEpochs.String())
if churnEpochs < 0 || err != nil {
churnEpochs = mgr.GetConstants().GetInt64Value(constants.ChurnEpochs)
}
