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.
Filter out spec helpers and test code from coverage reports.
This will prevent future changes reporting reduction in coverage
even when only adding additional tests.
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.
