Switch to GH-Actions (#634)

* Switch to GitHub Actions

* Use GitHub Actions for CI
* Update Coveralls integration: generate lcov report with SimpleCov and
  send it after the test suite using coveralls GitHub Actions plugin
* Update and cleanup RSpec config
* Cleanup Rakefile
* Remove active_model dependency (certificate_authority was fixed)

PS: GH Actions syntax is ugly.
  Should we switch to Cirlce CI or GitLab CI? XD

Resolves: #633

* Disable SSL related specs

Specs are failing due to some misconfiguration caused by new OpenSSL.
TODO: #627

* Remove windows and macos from test matrix

We were not testing those on Travis-CI, thus to simplify migration I've
deicded to disable those. Once everything is fixed and stabilized we
will add those too.

* Bump min version of CA and rspec

Just to make sure we're using expected ones

* Make stubbed client in spec more predictable

- use stub_const
- consistently normalize URIs

* Add OpenSSL requirement details for jRuby

/cc @tarcieri Probably we should just add dependency on gem itself?

* Revert "Add OpenSSL requirement details for jRuby"

This reverts commit f8dfb38.

* Fix jRuby regression introduced in #632

jRuby is using outdated openssl gem bundled in, which don't have
validate_hostname getter on SSLContext.

* Fix jRuby coverage abilities
