Automate checking of the security plugin installation

Is your feature request related to a problem? Please describe.
There was a recent pull request that was reverted because it broke the install_demo_configuration.sh script, this should have been picked up by the checks on the PR rather than being discovered after it was merged. Additional there should be manual testing requirements before merging pull requests of which this scenario was included.

Describe the solution you'd like
A new GitHub action workflow that configures opensearch, installs the security plugin from build, runs setup script(s) and makes sure the server is up and correctly configured.

Describe alternatives you've considered
Looked into how the integration tests are configured, but they don't allow triggering shell scripts.

Additional context
There is a good starting point for this effort by looking at the script used by the security dashboards plugin integration test script, see https://github.com/opensearch-project/security-dashboards-plugin/blob/main/.github/workflows/integration-test.yml
