tensorflow-io 0.8.0 release

[BryanCutler]

This is to start the planning for the release of 0.8.0 for tensorflow-io.

Here is the list of items for 0.8.0:

• Fix test errors in tf-nightly failure cases #431
• Update the version in setup.py
• Update README.md to add additional supported ops since 0.7.0
• Update RELEASE.md to capture 0.8.0 changes and version compatibility.
• Push *.whl files to PyPI.org, including macOS package.
• Release R package to CRAN (optionally).

Just wanted to get the discussion started for timing. I know there are lots of changes going in right now with the new IOTensor ops, and also the upcoming release of TensorFlow 1.15.0. It would be good to get down what is left to do so we can make a 0.8.0 release soon after TF 1.15.0 is out.

Created a branch R0.8, and PR #470 as a working-in-progress. The tensorflow==1.15.0 was supposed to be rebased last month though it looks like there is some delay. So we may have to wait.

In the meantime, we are switching master and nightly build to use tensorflow==2.0.0rc0, but keep R0.8 branch to use tf-nightly (latest version was from 08/21).

The new PR is in #472

[BryanCutler]

I think we need to fix the test errors in #431 before release also

[yongtang]

As tensorflow/tensorflow#33263 has been merged, I expect that TensorFlow 1.15.0 to be released in a couple of days (Monday or Tuesday).

We are good with PR #472 and is pretty ready for our v0.8.0 release.

All tests pass now. The candidate wheel files for 0.8.0 release are located in (Note build number 1990):

Will do some testing, if everything is fine, will label v0.8.0 release then push to PyPI.org (likely this afternoon).
