Rails 6 adds a new set of migration tasks for multi-database
apps. This change makes the annotate_models_migrate hooks
aware of them.

Add integration test that calls on rails generator.

This PR does the following:
* moves code coverage generation to happen when `COVERAGE` environment variable is present.
* makes integration tests run when when `INTEGRATION_TESTS` is present.
* moves `ruby-head` from TravisCI build. Previously the configuration allowed for `ruby-head` to be ignored if it failed, but it conflicted with the gem release build job step.

It was reported in https://github.com/ctran/annotate_models/issues/762 that column defaults were broken. This reverts changes made in #677 to restore the expected behavior of column defaults. 

For the time being columns with associated enums won't be working.

Adds integration tests to the project that's able to run in CI across different ruby versions.

* Adds a Rails 5.2.4.1 app
* Adds a Rails 6.0.2.1 app

Fixes #733 

There's some left over files from #725, this change cleans up the remaining files in `spec/integration/`.

`spec/integration` contains a lot of files that were used for integration tests. They stopped were [disabled in 2014](https://github.com/ctran/annotate_models/commit/9540121243da58cad3ab3c0ba444f22445a995ed#diff-78ddf877ecc2a9344997ef077a77955a) and haven't been working since.

Removing because those tests don't run, don't work, and are outdated. The plan is to re-introduce integration tests sometime in the future.

The scope of this pull request is to allow annotate_models to generate models documentation using YARD. This is the first step, I'll add more features later.
