Add support to release linux aarch64 wheels

[odidev]

Problem

On aarch64, pip install ml-metadata builds the wheels from source code and then install it. It requires user to have development environment installed on his system. also, it take some time to build the wheels than downloading and extracting the wheels from pypi.

Resolution

On aarch64, pip install ml-metadata should download the wheels from pypi

@hughmiao, Please let me know your interest on releasing aarch64 wheels. I can help in this.

hi @odidev , our wheels releasing build environment is based on pypa image manylinux2010: https://github.com/pypa/manylinux, looks we need to upgrade to manylinux2014 in order to release aarch64.

qq, are you using mlmd with tfx? if so, consider to open a bug on tensorflow/tfx, currently all wheels images are shared between tfx projects.

I'd appreciate if it would be possible to widen the platform support to ppc64le as well. However the same requirement also counts for that arch, as it is needs manylinux2014

@hughmiao, as per issue comment tensorflow/tfx#3829 (comment), ml-metadata has dropped tf dependency but here https://github.com/google/ml-metadata/blob/master/ml_metadata/tools/docker_build/Dockerfile.manylinux2010#L18 it looks like build tool requires tf image.

Please correct me if I am wrong or let me know if you are using a different wheel builder.

@BrianSong, can you please suggest on this comment: #114 (comment)

Hi @odidev,

Yes, MLMD OSS has dropped its tf dependency. The image you pointed out above is just a wheel image that we share between tfx projects. Do you encounter any problem when using it?

Hi @BrianSong,
Thanks for a quick reply. I am working on Linux AArch64 wheel build support. Can you please let me know if you have any plan for upgrading this tfx image to manylinux2014 and releasing for Linux AArch64 as well?

[BrianSong]

Currently this is under our radar but not in a high priority. We can easily update the image to manylinux2014, but as we are testing the build packages natively(without container), so we need put some effort to figure out a way to test aarch64 wheels in this setup(by running tests inside the container image.)

I wonder does Building manually from source work for you?

This is working fine but the availability of the wheel will save a lot of time of Linux AArch64 users.
