feat: Allow to restrict MintCoins from app.go (backport #10771) (#11227)
* feat: Allow to restrict MintCoins from app.go (#10771) ## Description Closes: cosmos/cosmos-sdk#10386 This PR adds feature to the bank module so that other modules using bankKeeper would be able to call the keeper with restricted permissions when minting coins. `WithMintCoinsRestriction` would be able to get called within app.go when setting keeper components for each individual keeper, taking a function that would validate minting denom as an argument. The example below demonstrates adding bank module with restricted permissions. ``` app.DistrKeeper = distrkeeper.NewKeeper( appCodec, keys[distrtypes.StoreKey], app.GetSubspace(distrtypes.ModuleName), app.AccountKeeper, app.BankKeeper.WithMintCoinsRestriction(DistributionMintingRestriction), &stakingKeeper, authtypes.FeeCollectorName, app.ModuleAccountAddrs(), ) ``` while there would be a seperate function that would restrict and validate allowed denoms as such. ``` func DistributionMintingRestriction(ctx sdk.Context, coins sdk.Coins) errors { for _, coin := range coins { if coin.Denom != ctx.NativeStakingDenom { return errors.New(fmt.Sprintf("Distribution can only print denom %s, tried minting %s", ctx.NativeStakingDenom, coin.Denom)) } } } ``` The sdk's simapp currently does not have any keepers that are to be changed with this implementation added, thus remaining unchanged in `app.go`.
