Create the CI and testing infrastructure for e2e testing. Running the ci task now will push the plugin and sidecar images to a local registry, start kind, install the CloudNativePG and cert-manager operators, and then install the plugin-barman-cloud one. No actual test is implemented. Signed-off-by: Francesco Canovai <francesco.canovai@enterprisedb.com>
