[MXNET-953] - Add ASAN sanitizer, Enable in CI

[KellenSunderland]

Description

Add ASAN support so that users can create ASAN builds of MXNet. These builds should help users more easily address memory leaks and buffer overflows.

Enable ASAN builds in CI to display memory usage errors.

Checklist

Essentials

Please feel free to remove inapplicable items for your PR.

• The PR title starts with [MXNET-$JIRA_ID], where $JIRA_ID refers to the relevant JIRA issue created (except PRs with tiny changes)
• Changes are complete (i.e. I finished coding on this PR)
• All changes have test coverage:
• Unit tests are added for small changes to verify correctness (e.g. adding a new operator)
• Nightly tests are added for complicated/long-running ones (e.g. changing distributed kvstore)
• Build tests will be added for build configuration changes (e.g. adding a new build option with NCCL)
• Code is well-documented:
• For user-facing API changes, API doc string has been updated.
• For new C++ functions in header files, their functionalities and arguments are documented.
• For new examples, README.md is added to explain the what the example does, the source of the dataset, expected performance on test set and reference to the original paper if applicable
• Check the API doc at http://mxnet-ci-doc.s3-accelerate.dualstack.amazonaws.com/PR-$PR_ID/$BUILD_ID/index.html
• To the my best knowledge, examples are either not affected by this change, or have been fixed to be compatible with this change

Iterating on some tests locally.

Note: ASAN likely requires privileged docker containers.

@mxnet-label-bot can you please add [pr-awaiting-review]

Why 7.3 is also needed?

[KellenSunderland]

Good spot. It's an error by the backport author. There's a dependency that is actually only available if you have both added.

[lebeg]

Maybe add cmake arguments -DCMAKE_CXX_COMPILER=/usr/bin/g++-8 -DCMAKE_CC_COMPILER=/usr/bin/gcc-8 instead? It would be more cmake'ish.

[KellenSunderland]

Thanks Anton. I'll give it a shot.
