Warning allowed dependency is unused in KMP Project

[vanniktech]

When I run the aggregation task licensee all of the tasks for each applicable plugin are ran. Since the configuration is shared there are some warnings:

> Task :core:licenseeJvm
WARNING: Allowed dependency 'org.jetbrains.kotlinx:kotlinx-serialization-core-iosx64:1.3.0' is unused
WARNING: Allowed dependency 'org.jetbrains.kotlinx:kotlinx-serialization-core-iosarm64:1.3.0' is unused
WARNING: Allowed dependency 'org.jetbrains.kotlinx:kotlinx-serialization-json-iosx64:1.3.0' is unused
WARNING: Allowed dependency 'org.jetbrains.kotlinx:kotlinx-serialization-json-iosarm64:1.3.0' is unused

Obviously, jvm does not need ios targeted dependencies.

In my project where I have a common module that's being used on Android, iOS & Server I get 96 of those warnings.

Not only is that a lot, actually removing a custom URL / license becomes impossible since I'd need to try it out, rerun everything.

Since the warnings come from the fine grained task, I guess the one solution would be to have custom logic inside licensee which does it's own validation without delegating to other tasks.

Another solution would be to have different configurations for each target.

I'm out the rest of the year. This will have to be tackled next year at some point.

Probably covered by #48, too.

Another solution proposal to mention is adding warning suppression options. Something like this:

licensee {
    allow("Apache-2.0")
    warnings {
        unusedAllowedIdentifiers = false
        unusedAllowedUrls = false
        unusedAllowedCoordinates = false
    }
}

I've made a proof of concept of such API: vdshb@304f273

Works perfect for me. It is for 1.7.0, because I need it for projects with previous AGP.

@JakeWharton Let me know if you interested in this peace of functionality. I'll try to make a proper PR(s) for 1.8.x/1.7.x.
An advise with project's test policies and how to avoid signing plugin during tests might be required, though.

You can hide warnings now with #285. To be released next week.

Works for me; hence closing this.
