etcd backup to s3 crashing the operator

[haroonb]

Hello I'm currently testing the etcd operator for our production enviroment and running into a few issues I'm not able to resolve.
I'm currently testing backup and restore, but the backup_cr I create crashes the etcd-backup-operator.

I'm trying to backup the cluster to a s3 compatible storage called minio.

I tried to use the new ForcePathStyle introduced in release 0.9.4, but I'm not sure if I'm using it properly.
I also had to modify the etcd-operator since our kubernetes version 1.17 extensions/v1beta1.

I compiled a gist of all the settings I'm using.
