Create GitHub Action for deploying to Artifactory

This commit contains a GitHub Action for deploying to Artifactory. It
is heavily based on the source of the existing Concourse Artifactory
Resource (https://github.com/spring-io/artifactory-resource). It
provides for GitHub Actions functionality that is equivalent to the
Concourse resource's out support.

+= Contributor Code of Conduct
+
+As contributors and maintainers of this project, and in the interest of fostering an open
+and welcoming community, we pledge to respect all people who contribute through reporting
+issues, posting feature requests, updating documentation, submitting pull requests or
+patches, and other activities.
+
+We are committed to making participation in this project a harassment-free experience for
+everyone, regardless of level of experience, gender, gender identity and expression,
+sexual orientation, disability, personal appearance, body size, race, ethnicity, age,
+religion, or nationality.
+
+Examples of unacceptable behavior by participants include:
+
+* The use of sexualized language or imagery
+* Personal attacks
+* Trolling or insulting/derogatory comments
+* Public or private harassment
+* Publishing other's private information, such as physical or electronic addresses,
+  without explicit permission
+* Other unethical or unprofessional conduct
+
+Project maintainers have the right and responsibility to remove, edit, or reject comments,
+commits, code, wiki edits, issues, and other contributions that are not aligned to this
+Code of Conduct, or to ban temporarily or permanently any contributor for other behaviors
+that they deem inappropriate, threatening, offensive, or harmful.
+
+By adopting this Code of Conduct, project maintainers commit themselves to fairly and
+consistently applying these principles to every aspect of managing this project. Project
+maintainers who do not follow or enforce the Code of Conduct may be permanently removed
+from the project team.
+
+This Code of Conduct applies both within project spaces and in public spaces when an
+individual is representing the project or its community.
+
+Instances of abusive, harassing, or otherwise unacceptable behavior may be reported by
+contacting a project maintainer at [email protected] . All complaints will
+be reviewed and investigated and will result in a response that is deemed necessary and
+appropriate to the circumstances. Maintainers are obligated to maintain confidentiality
+with regard to the reporter of an incident.
+
+This Code of Conduct is adapted from the
+https://contributor-covenant.org[Contributor Covenant], version 1.3.0, available at
+https://contributor-covenant.org/version/1/3/0/[contributor-covenant.org/version/1/3/0/]

+= Contributing
+
+This project is released under the Apache 2.0 license.
+If you would like to contribute something, or simply want to hack on the code this document should help you get started.
+
+
+
+== Code of Conduct
+This project adheres to the Contributor Covenant link:CODE_OF_CONDUCT.adoc[code of conduct].
+By participating, you are expected to uphold this code.
+Please report unacceptable behavior to [email protected].
+
+
+
+== Using GitHub issues
+We use GitHub issues to track bugs and enhancements.
+If you are reporting a bug, please help to speed up problem diagnosis by providing as much information as possible.
+Ideally, that would include a small sample project that reproduces the problem.
+
+
+
+== Sign the Contributor License Agreement
+Before we accept a non-trivial patch or pull request we will need you to https://cla.pivotal.io/sign/spring[sign the Contributor License Agreement].
+Signing the contributor's agreement does not grant anyone commit rights to the main repository, but it does mean that we can accept your contributions, and you will get an author credit if we do.
+Active contributors might be asked to join the core team, and given the ability to merge pull requests.
+
+
+
+== Code Conventions and Housekeeping
+None of these is essential for a pull request, but they will all help.
+They can also be added after the original pull request but before a merge.
+
+* Make sure all new `.java` files to have a simple Javadoc class comment with at least an `@author` tag identifying you, and preferably at least a paragraph on what the class is for.
+* Add the ASF license header comment to all new `.java` files (copy from existing files in the project)
+* Add yourself as an `@author` to the `.java` files that you modify substantially (more than cosmetic changes).
+* Add some Javadocs.
+* A few unit tests would help a lot as well -- someone has to do it.
+* If no-one else is using your branch, please rebase it against the current main (or other target branch in the main project).
+* When writing a commit message please follow https://tbaggery.com/2008/04/19/a-note-about-git-commit-messages.html[these conventions], if you are fixing an existing issue please add `Fixes gh-XXXX` at the end of the commit message (where `XXXX` is the issue number).
+
+
+
+== Working with the code
+If you don't have an IDE preference we would recommend that you use https://spring.io/tools/sts[Spring Tools Suite] or https://eclipse.org[Eclipse] when working with the code.
+We use Buildship for Gradle support.
+Other IDEs and tools with Gradle support should also work without issue.
+
+
+
+=== Building from source
+To build the source you will need to install JDK 17.
+The project is built with Gradle. Using the wrapper that is included in the project's source is strongly recommended.
+
+The project can be built from the root directory using the standard Gradle command:
+
+[indent=0]
+----
+	$ ./gradlew build
+----
+
+
+
+==== Integration tests
+Docker is required for the integration tests that run as part of the default build.
+If you don't have Docker installed, those tests will be automatically skipped.
+
+
+
+=== Importing into Eclipse
+You can import the resource's code into any Eclipse based distribution with Buildship, the Eclipse Gradle tooling, installed.
+
+
+
+=== Importing into other IDEs
+Gradle is well supported by most Java IDEs. Refer to your vendor documentation.
