Description of problem: When we disable a module with dnf module disable all other modules which are not disabled and depend on it trigger showing warnings. This happens on any dnf operation, even not related to modularity. For example: $ dnf module disable llvm-toolset <... output skipped> Modular dependency problems with Defaults: Problem 1: module rust-toolset:rhel8:8030020200807201053:d48633fe.x86_64 requires module(llvm-toolset:rhel8), but none of the providers can be installed - conflicting requests - module llvm-toolset:rhel8:8060020220204053142:d63f516d.x86_64 is disabled <... output skipped> $ dnf search smb Updating Subscription Management repositories.

The proposal is to disable also all dependent modules on module disable op. For example above, the operation 'dnf module disable llvm-toolset' should also disable rust-toolset module as well.

I think the request is valid, but fix would be very difficult. Disabled operation is not handled as remove but as an exclude, therefore it creates unsatisfied dependency. The change would require to change the scheme of modular solver (not deliverable during lifecycle of RHEL). As a workaround I suggest to manually disable `rust-toolset`.
