Install binary for non root user

[hkcomori]

I want to install rclone in the home directory of non-root user for personal use on a shared machine. (eg. ~/.local/bin/rclone) For this purpose, I'm happy if the binary location, owner, and group could be specified by variables.

The binary location will be able to specified by #65, but no other variables. It would be more consistent if location, owner, and group for binary could be changed, because config already allows same parameters to be changed.

I would also prefer that become: true be managed outside of the role, so that it can be executed by a non-root user.

Are such use cases acceptable in this role?
