Subject: AArch64 support
X-Git-Url: https://gerrit.akraino.org/r/gitweb?p=ta%2Fcaas-cpupooler.git;a=commitdiff_plain;h=fba8297f85315ba9293061c3acb3adb3c8b61490

AArch64 support

- spec: change hardcoded x86_64 arch to current platform arch;
- spec: bump dependency manager version from 0.5.0 to 0.5.4,
  the first golang/dep release to include arm64 (aarch64) bins;
- Dockerfile(s): download arch-specific golang/dep binaries;
- Dockerfile: Instead of pulling CentOS base images from dockerhub,
  create them from scratch from the official SIG-cloudinstance repo:
  http://artifacts.ci.centos.org/sig-cloudinstance/
- spec: Bump minor RPM version;
