Create containers multiarch manifest file to allow single container multiarch support

[naorlivne]

Expected/Wanted Behavior

The same image should be used by both ARMv8 & X64 architectures (and possibly other ARM types as CI/CD for those permits)

Actual Behavior

X64 has it's own image, ARMv8 has it's own image, the latest points to X64 alone & no docker manifest file exists.
