Resurrect CI / CD and make it nice

Subtask of https://github.com/tarantool/tarantool/issues/6056

There are several problems with CI / CD in vshard:

• It uses Travis CI, which going to be paid service (.org infrastructure will gone soon, .com has tight limits).
• CI on several Linux distros is red (I don't know exact reason).
• No package deployments to our new S3 infra (see https://github.com/tarantool/tarantool/issues/3380, https://github.com/tarantool/tarantool/issues/4947, https://github.com/tarantool/tarantool/issues/5494)

We also can improve our CI in the following areas:

• Verify vshard against different tarantool versions.
• Verify build packages across different OS.
• Run tests on Mac OS.
• Verify installation using a rockspec.

The plan is to implement CI / CD for vshard on top of the GitHub Actions infrastructure, resolve existing problems and make it a way more powerful.

Estimated as 3 days work with the idea to reuse smtp's CI / CD code after resolving of the following tasks: https://github.com/tarantool/smtp/issues/34, https://github.com/tarantool/smtp/issues/35, https://github.com/tarantool/smtp/issues/36.

I suggest to start from adopting fast_testing.yml from https://github.com/tarantool/tuple-keydef.
