Forward flags to yarn_install task

[Globegitter]

I thought I could install new packages via gradle yarn_install, e.g. by running gradle yarn_install packagename or gradle yarn_install -- packagename but I have not yet seen a way to do this. Is this supposed to be supported? And if not do you know if it would be possible to add support for this?

There's currently no support for it, but it could be written using https://docs.gradle.org/current/userguide/custom_tasks.html#sec:declaring_and_using_command_line_options
