Migrate to github actions as travis has switched to a process that will
require requesting minutes regularly for open source projects, and
current development is slow enough that this additional overhead is too
much.
Correct the generation of the line coverage following the example at
coverallsapp/github-action#29. Remove dependency on coveralls
gem as no longer needed if using the action.
Patch older versions of simplecov to contain a branch_coverage?
method to ensure working with simplecov-lcov.
fixes `bundle install` step from the README, currently broken by https://github.com/hashicorp/vagrant-spec/issues/41
```
~/src/vagrant-libvirt $ bundle install
....
Fetching git://github.com/hashicorp/vagrant-spec.git
fatal: Needed a single revision
Revision master does not exist in the repository git://github.com/hashicorp/vagrant-spec.git. Maybe you misspelled it?

Works fine now on my workstation with the new name:
```
Using vagrant-spec 0.0.1 from git://github.com/hashicorp/vagrant-spec.git (at main@b6b56c8)
Bundle complete! 10 Gemfile dependencies, 73 gems now installed.
```
Latest vagrant depends on a vagrant-spec release containing a more
recent dependency on childprocess than is supported for earlier releases
of vagrant.
Adjust dependencies to pin to the specific release of vagrant-spec if
the request version of vagrant is 2.2.7 or older.
Does not attempt to handle the situation where a version is specified
that cannot be parsed.
While it would be useful to test against newer versions of 2.2.x, it
appears this encounters a bug in upstream vagrant when installing in
dev mode see https://github.com/hashicorp/vagrant#11293
Therefore limit latest 2.2.x released version tested against to 2.2.4.
Add some basic spec tests for the WaitTillUp action class to lay some
foundations. Utilize vagrant-spec pinned to a known working commit for
tests to pass consistently until they provide releases.
Requires updating some of the rspec libraries and includes
sharedcontext.rb from the jantman/vagrant-r10k project on github.
