ICA simtests require an application to have both the controller and host modules.

[Taztingo]

Summary of Bug

The simtests for v8.x has forced chains to require both the controller and host keepers for ICA because their sim proposals no longer test for nil. There are chains that may not want both the Controller and Host. The Provenance team first noticed this when we were trying to run our sim tests after updating ibc-go to v8.2.1.

Expected Behaviour

A chain should be able to choose if they want the ICA Controller, ICA Host, or both modules.

Version

v8.2.x

Steps to Reproduce

Run simtests on a chain that uses ICA and the simtests will produce proposals for both the Controller and Host.
