MinioAdmin class uses deprecated mc commands

[nox-404]

Hi,
I've been looking at the MinioAdmin class that wraps the mc admin command and noticed some deprecation...

• mc admin policy add -> mc admin policy create
• mc admin policy set -> mc admin policy attach
• mc admin policy unset -> mc admin policy detach

I did not check if #1291 also address these problems too, but since it's not available yet the problem remain

Same issue as #1293 ?

I tested #1277 by running pip3 install https://github.com/minio/minio-py/archive/refs/heads/master.zip (getting latest from git vs using 7.1.15) and it seemed to resolve the issue, at least for my use case.

oh it seems I did not check thoroughly !
I got a patch on my end for that, so I'll just have to wait for the release in my distro to remove it.
