v0.x CI is broken

[leezu]

We can see the CI will pass seemingly randomly:

fail
https://ci.gluon.ai/blue/rest/organizations/jenkins/pipelines/GluonNLP-py3-gpu-integration/branches/PR-1521/runs/11/log/?start=0&download=true/*view*

pass
https://ci.gluon.ai/blue/rest/organizations/jenkins/pipelines/GluonNLP-py3-gpu-integration/branches/PR-1521/runs/10/log/?start=0&download=true/*view*

failure log

So far all failing runs were on

ip-172-31-43-211 │ip-172-31-19-212

whereas the successful run was on

ip-172-31-22-205

It may be due to mismatch in instance configuration.

@barry-jin would you have time to backport the Github Actions CI implementation to the v0.x branch? Then we can get rid of all the troubles with Jenkins

[barry-jin]

@leezu Sure.
