Changes proposed in this PR

During the CRT on-boarding, packaging for other Linux architectures (arm64) was not enabled. This change adds packaging support for those architectures. I've specifically opted not to include 32-bit.

Other related updates:

• To make future support a bit easier, I've enabled the build workflow from releng prefixed branches.
• Using qemu emulation for testing package installs on other architectures, thus allowing us to validate the binaries work as intended
• Minor alteration to the package install tests to use yum instead of rpm

Note: I tried to add 386/arm packages but pivoted away. There's something suspicious with the 386 binary specifically (see comments). Since usage of that architecture is low, I punted.

How I've tested this PR

Please note, these packages have not been extensively tested on their respective platforms. I did update the pipeline to run the smoke test (consul version) against the arm64 packages in an arm64 user-space. So I think it's in a good place.

How I expect reviewers to test this PR

Download builds and test in the same manner existing binaries are tested. Docker containers would be sufficient.

This probably needs to be manually backported as the automatic backport failed.
