No completions for method call expressions inside closures

[gayanper]

Is your feature request related to a problem? Please describe.
When trying to complete method call expressions, I don't get the completion items of that method call expression return value such as

spotless {
    java {
        googleJavaFormat().
    }
}

Completion behind googleJavaFormat(). This might only works up to this point after applying the PR #1337

Describe the solution you'd like
I would like to to get the list of completions for the return type of googleJavaFormat() instead of closure. One idea is to add all methods of the return type of googleJavaFormat() into the same closure list generated from GradleServer. May be we might need to change the name of the method then.

Describe alternatives you've considered
None

@jdneo @testforstephen What do you think about this feature, Do you have better solution ideas ? If so let me know I could find time to implement.

Another approach I thought of is, the gradle plugin part which generate the closure map can also keep the actual class as well connected to each entry. And when we want to resolve methods for the type in a expression, we could send a request to gradle server which will use the closure class's classloader to load the requesing type and provide methods and fields.

I think this will be a better approach that what I described above. WDYT @jdneo @testforstephen ?

sounds like the new proposal will only calculate the completion on demand lazily, is that correct?
