Description

We want to use this feature in Akash Network.

The Akash whitepaper defines a time-based function for the inflation: I(t). The way cosmos-sdk currently calculates inflation is different as compared to what the Akash whitepaper prescribes. So, we need the cosmos-sdk to accept a custom function to calculate inflation. When the custom function isn't provided, it should use the default inflation calculation logic as it currently does.

LGTM. it's a small API-breaking change, but imo useful.

## Description

We want to use this feature in [Akash Network](https://akash.network/).

The [Akash whitepaper](https://whitepaper.io/document/632/akash-network-whitepaper) defines a time-based function for the inflation: `I(t)`. The way `cosmos-sdk` currently calculates inflation is different as compared to what the Akash whitepaper prescribes. So, we need the `cosmos-sdk` to accept a custom function to calculate inflation. When the custom function isn't provided, it should use the default inflation calculation logic as it currently does.
