Update PostGres Oracle Foreign Data Wrapper image

The base image for our PostGres deployments is at: https://github.com/bcgov/openshift-postgresql-oracle_fdw

To update the image (e.g. update postgres startup parameters or perhaps new version of underlying software), update the GitHub repo and rebuild the openshift-postgresql-oracle-fdw image via the console.

After the successful build, we need to redeploy to each environment (moe-gwells-dev Note that each environment is distinctly tagged as either :dev, :test: or :prod; to actually redeploy using the new (:latest) image, you must tag the image.

oc project moe-gwells-tools
oc get istag | grep openshift-postgresql-oracle-fdw

Confirm that the SHA #'s are as expected (i.e. :latest is different from the others), and then tag the :dev image first:

oc tag openshift-postgresql-oracle-fdw:latest openshift-postgresql-oracle-fdw:dev
oc get istag | grep openshift-postgresql-oracle-fdw

Confirm that the SHA #'s are as expected (i.e. :dev is the same as :latest), and then monitor the auto-deploy on the console.

After the successful re-deploy, we need to repeat for :test.

oc tag openshift-postgresql-oracle-fdw:latest openshift-postgresql-oracle-fdw:test
oc get istag | grep openshift-postgresql-oracle-fdw

Confirm that the SHA #'s are as expected (i.e. :test is the same as :latest), and then monitor the auto-deploy on the console.

After the successful re-deploy, we need to repeat for :prod.

oc tag openshift-postgresql-oracle-fdw:latest openshift-postgresql-oracle-prod
oc get istag | grep openshift-postgresql-oracle-fdw
