Operator support for ARM64

[michaelhyatt]

Currently, there are no arm64 published binaries for the operator, so I tried to build it myself on Raspberry Pi running Ubuntu 64-bit server and the build fails on the UBI image mentioned in the Dockerfile.

Replacing the image with FROM almalinux:7-minimal AS ubi7 seems to be the way to fix it, since RHEL doesn't release arm64 images for their UBI7 images.

Not yet released 0.18.0 (in active development) available for ARM64 and switched to ubi8
