Add CI/CD

Exact same issue compared with here. Hunesion/ossFileTransferClient#19

At this point, I do not recommend using travis-ci. See security flaw: https://arstechnica.com/information-technology/2021/09/travis-ci-flaw-exposed-secrets-for-thousands-of-open-source-projects/.

Instead, I suggest to jenkins or Github Actions.
