KUDU-3079 Add MiniRanger

Apache Ranger has some setup scripts[1][2] that should be used to
install it but they touch a lot of things on the file system that
unfortunately can't be configured or $PREFIX-ed/chroot-ed, so we've
opted for a more manual approach similar to what Impala have chosen[3].

As Ranger 2.0.0 was released back in August 2019 which didn't contain
the Kudu service definition and it wasn't a clean backport I opted to
use the tip of the master (at the time of writing).

Unfortunately Ranger's scripts were written for Python 2 and there were
several compatibility issues with Python 3 so I had to patch it. Most of
the changes were generated by "2to3" but it required some manual changes
as well to run on Python 3.

I had to apply another patch to fix an issue running db_setup.py on Mac
as it runs ranger-admin-services.sh which sets the script path by
running `readlink -f $0` which doesn't work on Mac. Instead of rewriting
the script in a way that would work properly on Mac and Linux I opted to
use an environment variable instead, so I decided to use a separate
patch file for this as this one will need to be applied even after
Ranger decides to support Python 3[4].

Thanks to Andrew Wong for his help with the Ranger setup[5].
