Add CentOS 7 Docker instructions

[mohsenrezaeithe]

Fixes #1542

This is a starter kit to add support for building CentOS 7 based Docker images that'd be maintained in parallel to the Ubuntu based ones. There are some opportunities for refactoring or consolidation that can also be tackled that's not handled in the first version of this change (could possibly be done through follow up PRs).

Notes:

• Using the current instructions, CentOS 7 is diverged from master starting at 1a36026, i.e. this is using 4de4c7b to successfully build.
• The main difference between these CentOS 7 instructions and Ubuntu is Bazel 1.2.1 and Python 3.x.
• I may have narrowed down the problem to the version of gcc used for libtool out of the box:

  ---> Package libtool.x86_64 0:2.4.2-22.el7_3 will be installed
  --> Processing Dependency: gcc = 4.8.5 for package: libtool-2.4.2-22.el7_3.x86_64
  

A couple of errors that I wasn't able to fully resolve on master, hence the "starter kit" label:

I've also arrived at #1563 using the Development Tools group or a subset of that, e.g.:

ERROR: /root/.cache/bazel/_bazel_root/e53bbb0b0da4e26d24b415310219b953/external/grpc/BUILD:439:1: Linking of rule '@grpc//:grpc_cpp_plugin' failed (Exit 1)

A couple of follow ups:

1. CI/checks to build and publish an image for CentOS 7.
2. Figure out which of the GCC libs is causing the compatibility issue with Bazel 1.2.1, e.g. devtoolset-9, gcc-4.9.x, etc.

@mohsenrezaeithe I wonder do you have a Dockerfile to build TF Serving 2.3 under Centos7.8? thanks, I have an issue with the old libstdc++.so.6 version when running TF Serving 2.3 on Centos 7.8: $ ./tf23 --version ./tf23: /lib64/libm.so.6: version GLIBC_2.27' not found (required by ./tf23) ./tf23: /lib64/libm.so.6: version GLIBC_2.23' not found (required by ./tf23) ./tf23: /lib64/libstdc++.so.6: version GLIBCXX_3.4.21' not found (required by ./tf23) ./tf23: /lib64/libstdc++.so.6: version GLIBCXX_3.4.22' not found (required by ./tf23) ./tf23: /lib64/libstdc++.so.6: version CXXABI_1.3.9' not found (required by ./tf23) ./tf23: /lib64/libstdc++.so.6: version CXXABI_1.3.11' not found (required by ./tf23) ./tf23: /lib64/libstdc++.so.6: version GLIBCXX_3.4.20' not found (required by ./tf23) ./tf23: /lib64/libstdc++.so.6: version CXXABI_1.3.8' not found (required by ./tf23)

Any tips? thx

@weitian my last successful build was on the included Dockerfile, centos:7.7.1908.

If you're using the Dockerfile from this PR, you'd probably have to tweak the gcc version (and then devtoolset, if still necessary) to get Bazel to build successfully on CentOS 7.

There shouldn't be any major differences between CentOS 7.7 → 7.8/7.9.

Thanks @mohsenrezaeithe any update for 2.6?
