`Grant` is stored in the KVStore to record a grant with full context. Every grant will contain `granter`, `grantee` and what kind of `allowance` is granted. `granter` is an account address who is giving permission to `grantee` (the beneficiary account address) to pay for some or all of `grantee`'s transaction fees. `allowance` defines what kind of fee allowance (`BasicAllowance` or `PeriodicAllowance`, see below) is granted to `grantee`. `allowance` accepts an interface which implements `FeeAllowanceI`, encoded as `Any` type. There can be only one existing fee grant allowed for a `grantee` and `granter`, self grants are not allowed.

`BasicAllowance` is permission for `grantee` to use fee from a `granter`'s account. If any of the `spend_limit` or `expiration` reaches its limit, the grant will be removed from the state.

* `spend_limit` is the limit of coins that are allowed to be used from the `granter` account. If it is empty, it assumes there's no spend limit, `grantee` can use any number of available coins from `granter` account address before the expiration.

`feegrant` module introduces a `FeeGranter` flag for CLI for the sake of executing transactions with fee granter. When this flag is set, `clientCtx` will append the granter account address for transactions generated through CLI.
