travis: Drop support.

Following a change in the terms of use, free Travis credits are really
too low for a realistic usage by OVS contributors.
As a consequence, testing OVS with Travis has been abandoned by most
(if not all) contributors to the project.

Drop the Travis configuration from our repository, clean references in
the documentation and move GHA specifics to the association yml.

-Continuous Integration with Travis CI
--------------------------------------
-
-A .travis.yml file is provided to automatically build Open vSwitch with various
-build configurations and run the testsuite using Travis CI. Builds will be
-performed with gcc, sparse and clang with the -Werror compiler flag included,
-therefore the build will fail if a new warning has been introduced.
-
-The CI build is triggered via git push (regardless of the specific branch) or
-pull request against any Open vSwitch GitHub repository that is linked to
-travis-ci.
-
-Instructions to setup travis-ci for your GitHub repository:
-
-1. Go to https://travis-ci.org/ and sign in using your GitHub ID.
-2. Go to the "Repositories" tab and enable the ovs repository. You may disable
-   builds for pushes or pull requests.
-3. In order to avoid forks sending build failures to the upstream mailing list,
-   the notification email recipient is encrypted. If you want to receive email
-   notification for build failures, replace the encrypted string:
-
-   1. Install the travis-ci CLI (Requires ruby >=2.0): gem install travis
-   2. In your Open vSwitch repository: travis encrypt mylist@mydomain.org
-   3. Add/replace the notifications section in .travis.yml and fill in the
-      secure string as returned by travis encrypt::
-
-          notifications:
-            email:
-              recipients:
-                - secure: "....."
-
-  .. note::
-    You may remove/omit the notifications section to fall back to default
-    notification behaviour which is to send an email directly to the author and
-    committer of the failing commit. Note that the email is only sent if the
-    author/committer have commit rights for the particular GitHub repository.
-
-4. Pushing a commit to the repository which breaks the build or the
-   testsuite will now trigger a email sent to mylist@mydomain.org
