Arguments completion for standard tasks

[gildor]

Now completion doesn't for arguments of tasks. For example, default task wrapper has arguments --gradle-version and --distribution-type, but autocompletion doesn't work for them. Maybe it's a bigger problem: how to pass parameters to task using cli arguments without -D and -P and still be discoverable by a user, but anyway, standard tasks should have own argument completion lists.

Bash, Mac OS, Gradle 4.0

This is unimplemented only for Bash. Zsh completion works fine.
