[Feature]: Add -Params support to runsim

[fmorency]

Summary

The simulator supports initializing its state using a params.json file containing module and simulation parameters, as described in https://docs.cosmos.network/main/learn/advanced/simulation#simulator-modes (option no.3).

As a user, I want the ability to provide a params.json file to runsim so it can be forwarded to go test.

Problem Definition

Such initialization using a parameter file is currently unsupported by runsim.

Proposed Feature

Add -Params support to runsim

we are actually removing the current runsim tool and making it work directly with the go tool system. This should help suffice with your feature correct?

If the new system allows for setting the operation weights of a given module and perform runs in parallel. then yes, it would suffice.

Is there anything I can do to help?

we just merged the pr replacing runsim with the go test toolkit system. #20490. This should work for you now, closing the issue. Reopen if anything else is needed
